As Kuki said, just ask your TA to book you a guaranteed ocean view cabin. IMO, your TA should have explained the different ways to book when you first went in.
If you're having a problem with your TA, email me and I'll give you the name of our TA (brick & mortar) here in LR. We had a MAJOR problem with our first TA here (at an auto company ), but since then I found one of the best TA's ever!
