Don't mean to be the bearer of possible doom & gloom, but we've only gotten into BCV once in June. I'm a teacher & tend to head to WDW as soon as school gets out (early-mid June).
I've even tried to break up the stay between two resorts & had difficulty. I try at 7 months. I try waiting lists, but it's such a small resort that it's hard to get into.
We're trying for studios, so perhaps if you want a 1 or 2 bedroom you'll have better luck.
