I agree about the Wish, was not a fan but the Treasure is different in a very good way. One thing that helped the overall experience of the cruise was that the entire ship was full of veteran DCLers. I've never seen so many Pearl lanyards. Experienced cruisers definitely helped with the flow of everything. Downside was the nightly trivia related activities, get there EARLY

As a Star Wars fan, the Haunted Mansion bar was FAR superior :-(
They definitely are still working through initial sailing stuff, Aqua Mouse was out of service every day for most of the day. Be the first in line before it breaks down.
