I've cruised both Carnival and Disney with my children. If I were to choose Carnival and want the same quality of staterooms as Disney, avoid the older smaller ships. We have cruised both older and newer ships on Carnival. The Victory, Destiny, Triumph, and Pride all have suites with verandahs much like Disney. We cruised on the Triumph with 3 verandah suites and it was fine. Carnival's older ships have only a few verandahs. The older ship we took, the Holiday, our stateroom was really beat up with broken drawers etc. Carnival's ships are also more wildly decorative, some would say gaudy and tacky.
Also avoid the shorter cruises which attract more of the drinking and partying types. We were on a 7 day spring break cruise that was all families. Our children are older and don't spend much time in children's activities any more so I can't comment on Carnival's child program.
I enjoyed the food more on the Carnival ships. I thought the caliber of Disney's shows was better than Carnival's song and dance type. But I also enjoyed the comedians on Carnival much better.
It will be interesting to hear my children's input on the 7 day, coming June 29th.

PS When we took our spring break Triumph cruise, I also priced
Royal Caribbean Voyager,sister ship to the Adventure. It was thousands more for the 3 balcony cabins.
