There are alot of things we like and don't like about Disney.
We really like the ships, staterooms, amenities, interaction with the characters, and the fact there are 'adult-only' areas on the ship and the private island. We also like that we can bring beer, wine, and alcohol onboard the ship.
We absolutely LOVE the shows - they are amazing! And the private island is awesome (albeit the food wasn't all that good)!
But the two things we really don't like about Disney is the price - it's just too high and makes it tough on families. And we really don't like the food - that was definitely a disappointment. While the food in the specialty restaurant is very good, the rest of it was only okay. Considering what you pay for a Disney cruise, you would just expect better food.
But overall, as one person said, you're always a kid at heart no matter how old you are. We're 62 and really enjoyed our cruise on the Magic and can't wait to take our grandson on one of the newer ships.
