Best idea to start would be to read a few reviews on cruise critic and elsewhere online.. Cruise Critic has a search function.
go through the Celeb website which covers dining and other aspects of the ship.. with photos and has specifics as to classes of staterooms & their amenities.

We enjoyed BEYOND..loved the World Class Bar looking over all the action at the Martini Bar. Great Art on board..
Enjoy!
