Wonder: our favorite. Adult-only areas are perfect for us, Tianna's, the shows, the size, the multiple portholes you can sit in and their location, and its itineraries.
Magic: very similar, except I don't like Tangled.
Fantasy: we didn't expect to like her because we're not very fond of the Dream, but as cruising started back up after Covid, we got a great deal on a 3-night cruise so we tried her and very much enjoyed her! A little too big, like the Dream, but a much better adults-only atmosphere, though we miss the adults-only pool (the smaller ships have a larger pool). We're going on a 7-night on the Fantasy next month and I'm looking forward to seeing if she is indeed as awesome as she appeared on our short 3-night. If so, she might jump to #2.
