We sailed on the Wonder last year for a 5 day before dry dock. The work that they did was fantastic.
Cabanas (the buffet) is much more functional and much roomier than it used to be, never really had any trouble finding a table inside.
The kids areas - the Oceaneer Lab and Club were both much better than last year. We had difficulty getting our son to go last year, this year he didn't want to leave. The staff in the Nursery and activities for the under 2 year olds there were great, but activities for the young ones outside of the paid nursery service are a bit lacking - there is a toddler area but not much in it when there is not defined toddler time, and the Dory's Reef splashground also could have used a bit more flair.
First cabin with a verandah - was very nice, never felt like we were walking too far to anything. Deck 6 has just a long straight corridor, so if you walk aft on deck 6 to go to the restaurants, it does feel a bit long, but if you go up to 9 or down to 3 4 or 5 first it feels much shorter.
A little bit of noise, not really from the elevator, but more so from cabin attendants who seemed to congregate near our room.
Check in super easy, no issues.
A quick stop at the Fort to take a picture was only an opportunity to be assaulted by aggressive street vendors, including several who attempted to board our bus for people who didn't feel safe getting off. The children's pool was dirty, there were no lifeguards, and the public beach was also inundated with vendors, including one who tried to pull our child away in the water on a boogie board.
Overpriced even without the issues, you'd be better staying onboard.
