i think vero beach is sold out unless you buy a resale, or go on a waitlist from disney.
you can transfer points from one account to another, but your points that you transfer will remain its own home resort, its own use year, its own banking deadline, so no you can not book at the 11 month, you would have to book half of it at the 11 month and then the other half at the 7 month. or wait until the 7 month and book the whole thing. once you tranfer" IN" you cannot transfer "OUT" until your next use year, for example you transfer points from vb to ssr then you can only transfer INTO ssr and transfer OUT of vb until your next use year. once points are transfer you cannot not transfer them back it is a done deal.
