We are going in a few weeks and have been on the other 4. What is it you like?
You didn't ask me, but...my husband and I have a lot of stuff that we liked! We've also been on the other 4!
We liked the tiered look of the main deck with lots of smaller pools - an unpopular opinion, I think. We don't spend much time in pools, so quality/depth wasn't a big deal to us, we liked the layers.
We don't spend a lot of time in adults-only areas (although we're mid-40's with no kids), so the fact that it was out-of-the-way was not a disappointment to us.
Really enjoyed the Set Sail on a Wish (sail away party) and the new stage space on the Wish. Looking at videos of the Fantasy Sail Away Party (in preparation/dreaming of our upcoming May cruise), the set up with the banners/etc. actually looks pretty cheesy to us now.
LOVED the pool deck food - especially Donald's Cantina and the BBQ.
LOVED the Pirate Parlay Party and fireworks coming from both funnels.
We enjoyed the MDR - although I'll agree that they're crowded and lead to some service issues, we liked the theming/decor. I especially loved 1923.
We love just walking around, and a major complaint is the lack of a promenade deck that surrounds the ship, which I agree is a problem for those that want to run, but we still spent plenty of time out there. I really liked being able to go on the "front" of the ship (I think deck 6?)
While not a huge fan of the AquaMouse (much prefer the AquaDuck), I really liked that you didn't have to climb super high to get on and that you get on and get off at the same level. I'm not great at walking without shoes due to some physical issues and I was happy to not have to go far without them.
