We stayed this past weekend at the Signature suites.  Candidly, I really found it hit and miss.  We booked through Luxury Suites International, and you had to call them instead of the front desk for housekeeping and any issues.  Kind of a pain.  I will say that they did respond quickly to requests.\n\nThe rooms were fine and come with toiletries -- but don't look for any extras (like shower caps, swabs or cotton balls).  We left our rooms at 9am and when we came back at 3:00 pm they had not even been serviced and had to call down to get someone to come and do it (and yes, we did have the housekeeping light on).\n\nAlso, they do hold a strict 3pm arrival --- be aware of this.  We were told we could ask for an early arrival and pay a small fee -- but no dice on this.\nI will say that the staff were friendly and helpful, esp the guys by the bell desk and doing the valet parking, taxis. Also many thanks for recommending their own car service to the airport -- roomy trunk and inside, and the driver was great!  I totally recommend this -- about the same price as a cab -- but sooooo much nicer\n\nI will say that you don't get the smokiness in the hotel that a lot of the others (with casino attached) have.\n\nHaving said all this -- not sure that I would go back though.  It is a bit off the beaten path and some of the other Vegas hotels look interesting.
