Have cruised this class twice and will again in December. Have cruised every size ship and the amazing thing about Allure is that you don't feel crowed even with this many people on board. Truly an amazing experience.
We have sailed RCCL over 15 times on every class in the fleet. While we have always shave a great time after our first trip on Oasis we were sold on this class. The ship is big but because of they way it is laid our and with many public areas we feel less crowed than on some of the smaller ships.
The specially dining has become one of our favorite elements.
Cabins are nice and what you expect on a cruise ship. Have always found them to be well maintained and comfortable
