Hello Nathan,
Definalty check out the Ice show and Quest.. those are the only two i can suggest, i didnt make it to any others too busy checking out everything else.. BUT next March i will be sure not to miss a show..
This was my first cruise, and frankly i was in awe the entire time.. it was amazing and i dont think i wanna experience another ship lol.. i am spoiled with the Navigator

Happy Cruising.
