Everyone already knows about the Oasis. What it has, the size, the food, and so on. I experienced it all and it was great. I am working on a walkthrough video that took 45 minutes to see all the public areas; the ship is that big.
This boat makes you rethink cruising. We all thought about skipping a port because we've been there, I considered doing it so I could have the FlowRider (almost) to myself. This boat has something to offer everyone, and it is done so well that staying on the boat is a serious consideration from time to time.
Entertainment is nonstop. There are so many venues that there is something going on almost all the time. The daily schedules are so packed full that you get a additional page in your Compass (daily) for just evening activities. One example: Instead of just offering a great show like Hairspray, they also offer a dance class to learn the dances in the show. This is just one example, there are many more (and I'll be posting a full set of Compasses for the Eastern route).
