Possibility but it will be a challenge. That time is a prime spring break week; even though it is not one of the Easter weeks it is one that many schools have as their annual spring break week.
I would try to get the BCV reservation right at the 7 month mark. Keep in mind if a BCV home resort member is planning on changing their reservation at the 7 month mark the BCV reservations might not open up for a couple of days, but if you get your wait list in on the first day you'll have a greater chance of getting in.
It's also harder to get longer reservations versus 3 or 4 day reservations at the 7 month mark. So you could consider a split stay if you want a longer vacation. Good luck, here's a little to help you get your reservation.
