You can switch your BCV reservation to all VB points at 7 months if there is still availability for your room size. In effect cancelling the original reservation and rebooking. If the room you want is sold out, you cannot switch without getting on the waitlist. For example - you book a BCV 1 bedroom at 11 months with BCV points. You can switch it to VB points at 7 months if there is still a 1 bedroom available. If there are no 1 bedrooms available at 7 months, you can't switch it without getting on the waitlist.
