The Oasis really is unlike any other cruise ship I've experienced. It is massive! In some ways that is a strength and in other ways I think it is a weakness. A ship this size offers you options just not available on so many other ships, but it also loses (for me at least) some of the charm of cruising.
There is so much to do on the Oasis. You can surf, climb rock walls (nearly 80' high), zip line, ice skate, ride a carousel, mini golf, as well the normal things with swimming, shuffle board, jogging, gambling, dancing, etc. It's impressive all of the options available. We are not pool people, so I can't comment much on the pool situation.
The entertainment is also so diverse. From the Broadway show "Cats", the arial acrobatic, the high diving/gymnastics water theatre or ice skating, the musicians, comedians, Dreamworks characters, 3D Movies, game shows, etc it's hard to get board. The entertainment team must be huge! Overall, we were impressed with the talents of so many. The Royal Promenade (aka shopping mall) opens up the entertainment options as well with the parades and other events.
Overall a nice, quite cabin. The bed was painfully hard. The location was convenient to most of the activities.
Other than traffic getting dropped off the embarkation process was smooth and efficient.
It's like most other private beach/islands. It's beautiful.
Shaw Falls and Gardens is beautiful but not well maintained. The facility is starting to show it's age. We had lunch on the beach, but it was minimal and really not that good. The shopping was in this little shopping center that frankly was a waste of time. The tour guide was excellent.
