Isn't Cabanas already available for just that thing? And with so many food options already available, that wouldn't be my first priority. As others have stated the pools could be bigger. (Heck, the Quiet Cove Pool on the classic ships is already way bigger than on the Dream Class ships.) One thing I DO NOT want to see is
DCL just picking up ideas from other cruise lines and copying them. Disney, as a whole, is founded on the concept of innovation. So, instead of copying other cruise lines, I hope they wow us with something totally outside the box and new. Also, I hope they don't just throw in lots of extra things designed to suck more money from their guests. That will turn me off quicker than anything.
