This was our 9th cruise, our 3rd with RC and our 1st on Oasis class. The ship was as impressive as everyone says - absolutely amazing. You'll never run out of things to do (despite trying our best, we never got around to a couple things). The diving and skating shows blew our minds - by far the best shows we've ever seen at sea. CATS was boring like everyone says - the talent was there, just no plot.
Food was amazing, except the ranch dressing. Other than that, no complaints. We ate in the Main Dining Room most nights. Windjammer food was just as good but the place was way too crowded. Lines to get in and fighting for tables kind of ruined the experience.
Service was generally subpar. Our waiter on the first night was slow and rude, we asked for a change the next night and they were much better. Our cabin steward never introduced himself which blew us away. We ran into him in the hallway like on night 4 and he was nice enough, but I was disappointed by the lack of introduction. Also, we only got 3 towel animals the whole 7 night cruise! Across the ship, staff seemed generally annoyed to speak with us or help us and I got the impression that folks were pretty miserable.
The fellow cruisers were worse than the service. Very few English speakers on board and lots of other cultures came across as very rude. So much loud yelling in foreign languages, cutting in lines, plowing through people in crowds, shoving you aside, etc. Being raised in the American South, my husband and I were pretty flabbergasted. Usually we don't pay much attention to our fellow cruisers but on this ship the rudeness was pervasive. In addition to the attitudes, we didn't like the thong bathing suits everywhere. From old to young, male to female, tiny to very very plus sized, they were everywhere. So gross. A crew member told us the cruisers were always rude because so many foreign people want to sail on Oasis because it got so much international media attention after shattering the world record for ship size.
Embarkation was crazy fast & we were very surprised with how easy it was given the ship's size. We were on in less than 30 minutes.
Cabin was fine for an interior. Bed near door, couch and desk further inside. Not noisy except for our own sliding closet door slamming open and shut while we slept when the ship was rocking - major design flaw. Tube shower was cool. Closet had lots of storage.
