HI, We did it on our cruise last Feb. Four of us.. It was $400.00 deposit on our next cruise (we had a balcony). A $200 on board ship credit was what sold us. We we made this deposit we knew that our next cruise would not be until late 2010 and were worried cause the schedules were not out yet. Fast forward to a few weeks ago when we called our travel agent. She had all the info regarding the $400 deposit and applied it w/o any problems.
