The only ship we haven't sailed on is the Wonder.
The people who are intent on disliking the Wish will continue to voice their opinions as loudly as possible. We felt the level of service on the Wish was just as impeccable as the other 4 ships we've sailed on. With DCL its always been "Where do we want to go?" Which i what usually decides the ship for us.
We are at 8 cruises, another lifetime away from Pearl. It would have been nice to see a few more upgrades in perks (Free laundry, free Remy/Enchente, or even an OBC?) but at the end of the day, all companies are slimming down their free offerings and making rewards more challenging to use. The photos is a nice savings if you use it. That's $200 bucks per sailing so not terrible. We don't take enough pictures for that but some certainly do.
At the end of the day, Disney has every right to offer whatever they want for their Return cruisers. They could offer nothing at all and we would just have to deal with that. If you want different perks, you'll have to sail with a line that offers them. I doubt we'll see any sort of change in this regard on Disney's side anytime soon.
