I am currently sitting on my ocean view balcony about halfway through the Wonder's Eastern Caribbean itinerary. Clearly the wifi package is working beautifully! This is my first experience on the Oasis Class or larger, so some preliminary thoughts.
I miss the open water views on the promenade deck (deck 5.) Now it is primarily a jogging track with views almost entirely obscured by the lifeboats except for the aft section. It's a great boon for joggers, because threading through the sunbathers above the pool was never a viable option. Now deck 6 can have balconies because lifeboats moved down. I understand the reasoning, just really miss after dinner strolls.
Entertainment is amazing. Period.
New menus are good.
I feel like in general this class of ship has its emphasis inward: the promenade, central park, even boardwalk with very little reminding you that you are at sea.
Solarium is positioned nicely forward. Not as stuffy as some posters have mentioned. It's a little loud at times.
Overall, I would cruise on this ship again, but I think my favorite size is voyager class.
A day at sea beats a day at work anytime!
