Oasis of the Seas is a literally a sailing city! The ship has so much to offer, no matter what your interests are -- shopping, food, karaoke, gambling, entertainment, clubs, pools, lounging, surf simulators, kid's areas, etc.
Despite the amount of guests on the ship, our meals were always hot and pretty tasty. There were always many options to pick from and it was almost recommended that you try multiple meals/desserts. We chose the anytime dining option, that way we weren't locked into a specific time if we were too busy to get ready for dinner.
We packed in so much, that we were all exhausted when we got home -- that was our choice, and obviously you could just lounge by the pool if that's what you'd prefer. We saw Hairspray, the ice show, a comic, the Aqua Theatre show and an Abba cover band, on top of three excursions; The Bahamas, St. Thomas and St. Maarten. We took the glass bottom boat tour, which was mediocre. The tour guide was great, but the actual tour was just so-so. St. Thomas was beautiful and we had a great tour guide. St. Maarten was okay, but if you're into shopping, you'll like it.
The crew could not have been nicer! We were always treated as if we were the only ones on board.
I shared an Ocean View Balcony Suite with my two sisters, and had a decent amount of space. Two twin beds pushed together (you'd never know it wasn't one bed) and a fold out couch took up most of the room, however, the fold out bed was easily put back to a couch to allow for more space, and housekeeping folded down the bed each night.
The one and only thing that wasn't perfect was the weather, and that had nothing to do with the cruise. A little bit rainy and cloudy, but still some nice days too.
I would love to go back for another experience!
