Gave myself an upgrade!

We are cruising on the Oasis Feb '14, we have 4 rooms booked 2 of which I am paying for. I was just on the RC site surfing around and was able to switch both rooms from deck 10 inside, to deck 9 Central Park view for $100 less per room. One reservation is paid off and showing a $100 credit, the other still has a little bit left on it and did go down $100. Can I move that $100 credit onto the other reservation or will they keep it a room credit? What do you think of the Central Park view rooms? Deck 9 should be pretty quiet.

 

Thanks!
