Our chef, Deboran, showed me photos she had taken when the ship was in Glacier Bay, Alaska earlier this year. My mother had never been on a cruise before, and was ready to stay on for the next cruise. I've been a cruise expert for almost 10 years, and worked aboard one of the larger ships in Alaska as an entertainer back in 1986. I talked to many of the passengers on our cruise, and was surprised to find out that many were first time cruisers. Average age was probably 45, but my mother at age 68 was probably the oldest.
Typical passenger is more active, and creates their own fun, rather than waiting to be entertained.
Virtually no entertainment aboard, except for one silly game the crew ran one night. You get your entertainment from the scenery going by. Our room was on top deck, and separate from the rest of the boat structure. You create your own fun onboard these ships. Crew works very hard.
