Yes, we have been talking to them. I agree, I don't think they will allow us to switch "for free," We would probably need to forfeit the original payment and pay for the new reservation. The problem is that the ship is full (it's full every week in August). The only way we can get on the August 9 departure is to find someone who will cancel their reservation because they want to be on the August 16 departure. If we mutually contact RCI, I think it would work.
I will continue to call RCI in hopes that they will tell me if something becomes available. I have asked them if I can be on a "wait list," but they say it does not exist. I have also asked them to let me know when they have a cancellation but they said they do not provide such a service. I am certain that there will be last-minute cancellations (it is statistically impossible that all 5000 people will make it to the cruise)--I just don't know how to get one of the cancelled rooms unless I personally find someone willing to cancel.
Any suggestion or thoughts are greatly appreciated.
