We did the Allure and while we found the cruise to be very nice overall, we were disappointed in the food in the main dining room. I guess it's just hard to serve 6500 people in a few hours and still maintain a high level of quality. While the food was not bad, I feel they have declined in quality over the last 15 years. With that said, their specialty restaurants are still very good and we really liked them alot. Shows were very good and there were lots of things to do. Good thing was that we never really felt crowded for being such a large ship with so many people.
For younger people, this is an awesome class of ship with alot of amenities. And while we really enjoyed it, being an older couple (62), personally we much prefer the Solstice-class ships of the Celebrity fleet. Much better food and more sedate, which is more appealing to our lifestyle. But our kids absolutely love RCCL, so if you fall within a little younger crowd than us, I think you'll find this a wonderful cruise.
