                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   BASIS OF PRESENTATION AND OPERATIONS

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three month period ended March 31, 2000
are not necessarily indicative of the results that may be expected for the year
ended December 31, 2000.

The balance sheet at December 31, 1999 has been derived from the audited
financial statements at that date but does not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements.

For further information, refer to the consolidated financial statements and
footnotes thereto included in the Company's annual report on Form 10-K for the
year ended December 31, 1999.

Sonesta Beach Resort Anguilla reopened on February 10, 2000, after a brief
closure due to damage sustained by hurricane Lenny, which struck the island in
November 1999. Under its insurance agreements, the hotel will receive loss of
income proceeds for the period of the closure, as well as for a six month period
following the reopening date. The loss of revenue during the first quarter of
2000 compared to the same quarter in 1999 was approximately $1,056,000. Included
in gain from casualty is an initial payment of $500,000 which the Company
received against its business interruption claim.

In March 2000, the Company received a commitment to refinance its hotels in Key
Biscayne, Florida and Cambridge, Massachusetts. A closing is scheduled for May
30, 2000. The net proceeds from this refinancing will be approximately
$27,000,000, and the Company intends to use these proceeds for improvements to
the Key Biscayne property, and to fund its expansion plans. At December 31,
1999, the mortgage loan on the Key Biscayne property was classified as a current
liability. As a consequence of the aforementioned commitment, this debt has now
been reclassified as a long term liability. The current portion of long term
debt at March 31, 2000 includes the anticipated repayments on the new loans,
based on the terms of the loan commitment.

was outstanding under this line at March 31, 2000.

A subsidiary of the Company has a $5,000,000 line of credit which will expire
December 31, 2000. The terms of the loan require certain minimum levels of
earnings and net worth, limit cash dividends and purchases of the Company's
stock, and specify a maximum defined debt to net worth ratio. The loan is
secured by the Company's leasehold interest in the Royal Sonesta Hotel New
Orleans, and by a Company guaranty. The interest rate is prime (9% at March 31,
2000) less one-eighth percent, and the commitment fee on the unused portion of
the line is .65% per annum. An amount of $3,200,000 was outstanding under this
line at March 31, 2000.

A foreign subsidiary of the Company has a $400,000 operating line of credit and
a $600,000 non-revolving loan, both of which will expire on May 31, 2000. The
interest rate on the non-revolving loan is LIBOR plus 2.25% (8.125% at March 31,
2000), and the rate of the operating line of credit is based on the bank lending
rate plus 1% (11% on March 31, 2000). At March 31, 2000, the Company borrowed
the full $600,000 under the non-revolving loan, but had not utilized the
operating line of credit.

Total revenues for the first quarter ended March 31, 2000 were $28,242,000
compared to $26,630,000 in 1999, an increase of approximately $1,612,000.

Revenues during the first quarter of 2000 at Sonesta Beach Resort Anguilla were
$923,000 compared to $1,979,000 during the same period in 1999. The Anguilla
resort was closed due to damage sustained by hurricane Lenny from November 17,
1999 until February 10, 2000. The Company has insurance for the loss of income
during the period of closure, as well as for the reduction in revenues for a six
month period following reopening. Sonesta Beach Resort Key Biscayne had a slight
increase in revenues of $110,000 during the first quarter of 2000 compared to
1999, which was due to revenues from the hotel's retail shops, which have been
operated by the Company since late 1999. Room revenues slightly decreased,
mainly due to the fact that the first quarter of 1999 benefited from the
Superbowl, which was held in Miami in January of that year. Revenues at the
Royal Sonesta Hotel Cambridge increased by 27% during the first quarter of 2000
compared to the same period in 1999. Room revenue per available room (REVPAR)
increased by 25%, due to both higher occupancies and an increase in average rate
achieved. This increase in revenues was caused by higher demand from both the
group and convention and as well as the transient market segments. Revenues
during the first quarter of 2000 at the Company's Royal Sonesta Hotel New
Orleans increased by $1,167,000 compared to the first quarter of 1999. This was
due to a 12% increase in the hotel's REVPAR, and a 14% increase in food and
beverage revenues due to higher occupancies at the hotel. Revenues from
management activities increased from $1,115,000 during the quarter ended March
31, 1999 to $1,225,000 during the quarter ended March 2000. This was caused
primarily by increases in fee income from the Company's managed operations in
Egypt, in particular from the Sonesta St. George Hotel in Luxor and the Sonesta
Nile River cruise ships.

</TABLE>


Operating income for the three-month period ending March 31, 2000 was
$3,340,000, compared to operating income of $3,689,000 in 1999, a decrease of
approximately $349,000.

Operating income at the Sonesta Beach Resort Anguilla decreased by $1,094,000
during the first quarter of 2000 compared to the first quarter of 1999. This was
the result of a $1,056,000 decrease in revenues, due to the closure of the
resort from damage sustained by hurricane Lenny from November 17, 1999 through
February 10, 2000. The Company has insurance for this loss of profits, and has
already received an initial payment of $500,000 towards its claim for lost
income following this casualty. Royal Sonesta Boston (Cambridge) had operating
income of $346,000 during the first quarter of 2000, compared to an operating
loss of $320,000 during the first quarter of 1999. Revenues rose $1,281,000
compared to last year, and this increase was partly offset by increases in
expenses of $615,000, primarily in cost and operating, as well as depreciation
expense. Royal Sonesta Hotel New Orleans increased operating income from
$811,000 in the first quarter of 1999 to $1,221,000 in the first quarter of
2000, due to a $1,167,000 increase in revenues, partially offset by an increase
in expenses of $757,000. This increase in expenses was primarily in cost and
operating expenses, real estate taxes, and an increase in rent paid under the
lease under which the Company operates the hotel. Operating income at Sonesta
Beach Resort Key Biscayne decreased by $646,000 to $2,578,000 in the first
quarter of 2000 compared to last year. This was due to increases in expenses of
$756,000, primarily due to increased cost and operating expenses, which were
partially related to the hotel's retail shops, which were taken over by the
Company in late 1999. In addition, the hotel had an increase in depreciation
expense of $218,000 in the first quarter of 2000 compared to last year, which
was a result of substantial investments in property improvements and furniture
and equipment the Company has made following the hotel's acquisition in July
1998. Operating loss from management activities, which is computed after
management and service fees to the Company's owned and leased hotels, decreased
from $390,000 in the first quarter of 1999 to $75,000 in the first quarter of
2000. This was mainly due to increased income from the Company's managed
operations in Egypt.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION (CONTINUED)


OTHER INCOME (DEDUCTIONS)

Interest income during the first quarter of 2000 decreased by $21,000 to
$131,000, due to a reduction in interest earned on the Company's lower cash
balances. Included in the quarter ended March 31, 2000, is a gain on casualty of
$500,000, which represents an initial payment received by the Company on its
insurance claim for lost income following hurricane Lenny, which caused the
Sonesta Beach Resort Anguilla to close from November 17, 1999 to February 10,
2000. The Company's insurance policy covers lost income during the period of the
closure, as well as for a six month period following the reopening.


FEDERAL, FOREIGN AND STATE INCOME TAXES

The provision for income taxes during the first quarter of 2000 was higher than
the statutory rate due to state taxes provided on the Company's income from its
operations in Louisiana, Florida and Massachusetts.


LIQUIDITY AND CAPITAL RESOURCES

The Company had cash and cash equivalents of approximately $3,040,000 at March
31, 2000. The Company also has $8,000,000 available under three lines of credit,
of which $4,800,000 was utilized at March 31, 2000.

In March 2000, the Company received a commitment to refinance its hotels in Key
Biscayne, Florida and Cambridge, Massachusetts. A closing is scheduled for May
30, 2000. The net proceeds from this refinancing will be approximately
$27,000,000, and the Company intends to use these proceeds for improvements to
the Key Biscayne property, and to fund its expansion plans. The current portion
of long term debt at March 31, 2000 includes the anticipated repayments on the
new loans, based on the terms of the loan commitment.

The Company believes that its present cash balances, plus expected cash flow
generated from operations and from the aforementioned refinancing, will be more
than adequate to meet all of its obligations.


                                 PART I - ITEM 3

QUANTITATIVE AND QUALITATIVE DISCLOSURE OF MARKET RISK

in Key Biscayne, Florida and Cambridge, Massachusetts. The terms of the new
loans are further described in Note 4 - Long Term Debt.
