There are a variety of things that appeal to some and not others.
Lounge theming
Movie theaters - I love the big Buena Vista Theater and have watched many movies there. Wish introduced two tiny viewing rooms. I don’t anticipate using them.
Pools - the multiple small pools on Wish+ with steps, not just ladders look like a better option than one human soup watering hole. But their adult area gets a lot of down votes for multiple reasons. People seem to enjoy the adult exclusive outdoor area of Dream+ in with Satellite Falls.
Here’s my routine. Consider what you would want to do on your single or two sea day(s) and nights.
I spend a cruise eating breakfast and lunch in the buffet. On Wish+, I would venture out to the pool deck for BBQ or Mexican QS. I have a complimentary dinner on Pirate night (that’s my choice) in adults-only Palo (thanks to spending lots of time on
DCL). I like to watch a movie in the theater (late night) or on the pool deck (FunnelVision).
I go to the shows, walk around, get off in ports (if one of your options - both islands). I don’t rush out in the morning, but will hang there until closer to leaving time, when the crowds are essentially gone. I don’t do excursions at the beaches anymore, just enjoy the water. I have been known to just go at lunch time, as 90 minutes of sun is as much as I am allowed. I eat lunch at the adults-only Serenity Bay BBQ - unless I am pushing the end of lunch window on Castaway.
I play trivia several times a day - Fantasy has a good venue for that; my family said it wasn’t large enough on Wish.
Then I watch character meet and greets. Seeing happy children and knowing how nice the characters are is enough for me. I don’t take up time and space when so many really want the interaction. I don’t know of any ship where there really is a difference in line wait time. And I enjoy seeing them “in the wild,” in the halls.
I like to go on Deck 4 Promenade for sunsets. If it’s Dream+, I will often walk the loop of the ship’s length. That’s not an option (without stairs) on Wish+. I don’t need something to discourage me from walking.
Actually, most of the above, the general idea, is the same for me no matter the cruise line. I just end up seeing different places in the world.
Have fun thinking and deciding.
