This is Odyssey's best feature over Oasis. The Music hall, where I spent a lot of time, is so much better.
Also, to the OP...
I love both ships but wouldn't for a second hesitate to book Odyssey. You don't have the ice show or aqua show but you have the iFly, Northstar, bumper cars and Zone zero which are absent on Oasis class, Effectors is a cool high tech show and 270 is a phenomenal venue for many different things.
The Seaplex with Playmakers overlooking it is another great place to spend time. You can't go wrong with either. Why not shake it up a bit and try something different.
