VGC is very small. If you don't own there the closer you made the reservations to the the 7 month mark the better. If you do own there, how long have you been on the WL, close to your 11 month window? As well as PP asked, the amount of days matter. The shorter the WL the better your chances. People have posted here that when making reservations exactly at 7 month what they have wanted has not been available and they have had to WL.
I am sure someone who has WL at VCG will chime in, hopefully you have a back up plan just in case the WL doesn't come through. Good luck!!
