We had Spiderman on our cruise at the end of January.
Verandah staterooms on the Wish are the same size as on the Fantasy and Dream (which are all smaller than those on the Magic and Wonder). I definitely notice the difference between the Magic and Dream/Triton classes. It felt to me like the staterooms on the Wish were bigger than those on the Dream class even though I knew that they weren't but I think that's because the way they've designed the room with the TV on the wall instead of on the desk, removing the vanity/dresser unit with the wall shelving above that is beside the closet on the other ships and the removing the coffee table in front of the couch has made it feel more spacious. Which is nice, but I didn't like that it reduced the useful storage (no drawers, and just shelves in the closet). I used to put my feet up on the coffee table especially when watching TV but it's also now difficult to watch the TV from anywhere but the bed so I guess that's a moot point (except that I'm annoyed that I have to watch it from the bed).
