Don't let the complainers scare you off. If the Wish is the ship that appeals to you the most, go for it. A lot of the stuff people complain about don't matter to me at all. I took the complaints I read with a grain of salt, went on myself and made up my own mind. It's a departure from how Disney have done their ships, so there are bound to be some who prefer the old style.
Personally I'm glad they built in a different style, even if they didn't hit every single mark. We already have 4 in the "classic"
DCL style, we didn't need another one IMO
