Great report, very informative!
I have been on two RCCL cruises with my husband, and now have our first
Disney cruise coming up in February and we are bring the kids. Your comparisons were helpful to keep my expectations in check. When comparing staterooms, I have always compared the D classes on RCCL with the Category 4 on Disney, so the category 4 will be about 100 sq ft bigger. It is a cruise ship, so I expect to be crowded!
There are a few things I have already heard are different that I'm not thrilled with; the lack of the interative TV that RCCL has (I don't remember the exact name of it) that lets you check your account on the TV in your room, book excusions, order room service etc. and no atm on board, or (casino for that matter where you could get cash and charge it to your room account!). But, I'm taking this cruise for my kids, and will have to give somethings up for them!!
One thing going for Disney, their staterooms for 5 have a balcony, and there are lots of them. RCCL ships have a few cabins in the FF category that sleep 5 but they don't have a balcony and there aren't many of them. (I can't afford the suites on either line!)
