This was my 5th cruise but first time on Disney. All the other 4 times were on Carnival ships. While I would not go on Disney without kids, it was great for people that are cruising with kids. We brought our 4 year old and he had a great time.
The service was world class and they do cater to children but still take care of the adults too. The food was average for a cruise, some of the best things were the chicken strips for the kids and the beef tenderloin for the adults. The only thing that we didn't even finish was the turkey in the Triton restaurant.. it was dry and chewy... like rubber. Our son's favorite was the self service ice cream machine on deck 9.
Our son went to the kids club about 6 times and he had a great time. There is a small on-board arcade called Quarter Masters that our son liked to play in but it is small and some of the games were too big for him like many of the driving games, he couldn't reach the pedals. Also, on the last day of the cruise about 1/3 to 1/2 of the games were broken.
The cabin was nice for a cruise ship room... it was on the small side but not too bad. It was nice to have the balcony with the glass wall so that our 4yr old could see out also.
