My husband and I are 35 & 39 with no children. We have been on about 12 cruises- all Caribbean. We are now divers but enjoy all adventure tours. Onboard, we usually don't see the shows but enjoy talking with fellow passengers, reading, laying in the sun and keeping the bartenders busy.
We always fly to Florida one day ahead in case bad weather in Michigan delays us. We stayed at the Courtyard by Marriott Downtown Tampa and it was EXCELLENT! I booked it online with confidence because others had given it great ratings. I will do the same. Everyone was extremely friendly and helpful. Even the young guy busing dishes smiled and wished us a great day. Royal Caribbean's Grandeur of the Seas was built in 1996, but looks fabulous! We like the Radiance class ships best (included Brilliance of the Seas, Jewel of the Seas, Serenade of the Seas, and of course Radiance of the Seas). But the Grandeur was nearly as nice except for the gym (very small with limited equipment) and the "aftermarket" rock wall.
All food was great, but we are not especially hard to please. The dining room was especially nice with a live musician providing relaxing background music. Grandeur of the Seas does not have Portofino's, Chops Grill or SeaView Cafe, however the pizza, hot dogs and burgers in the Solarium were top notch, really!! The Windjammer is very bright and provides fantastic views of the ocean- much nicer than any Windjammer we've been in on the Voyager class ships. The food options at breakfast were plentiful but were the same every day.
