We booked a 7 night cruise for this December onboard last month. Well that is not going to work for us and we are now looking at late May 2007 when there are not any 7 night cruises. We are thinking about switching to a 4 night with a few days at WDW. Will it be possible for me to switch my onboard booking discount and stateroom credits over to a 4 day cruise or will we lose everything? Thanks!
