My wife and I joined family members for a planned three generation cruise. We have both sailed to Alaska from our hometown of Seattle before on Holland America, but this was our first experience on a Disney ship.
Staterooms - Well designed for families, certainly ample space in our 4A room for two people. Wave phones make communication easy on ship but we didn't really use them. TV shows the same movies over and over, but at least in the Alaska voyage carried more cable channels than we were used to on other lines. Room stewards were great, left towel animals every night along with chocolate. Biggest complaint was that our suitcases didn't fit under the bed.
Entertainment - The Dreams show was great, and I also would recommend seeing Toy Story. Others had mixed appeal since the audience was geared toward families. The ship band was quite good, the assistant cruise director did a wonderful job running trivia games. Adult entertainment after 10pm was readily available and surprisingly well attended.
