I'm sure this has been asked before but my search skills don't seem to be up to the task. 
Do you have to cancel your existing stay to book a new one at 7 months? i.e. We book at our home resort at 11 months, and want to try for a different resort at 7. Aren't all our points tied up in the first reservation? Do we have to cancel it first to book the new stay? And if so doesn't that risk us ending up without either one?
I'm shopping and trying to decide between resorts and contract size, and I'm assume that we'll want to try some other resorts. Looking at the availability charts we should be able to move around to a lot of the places I'd like to try. We have kids in school and actually want to plan at 11 months. But it seems like we'd probably never want to try and switch if its going to cost us our reservation at our home resort.
Thanks
