Whoops. I went off topic for a bit. AAnnie....thanks for the reply. Great discussion.
Okay actual question. I truly don't believe summer will ever be a "big" problem. However, there are a lot of young families joining
DVC these days. So that could change everything.
I booked BCV less than 5 months out last July without a problem. However, it was one bedroom. And one bedrooms, at every DVC, are the easiest bookings.
Also, I just looked into a June booking and July booking. Two bedroom. July, every DVC was open, right up to BWV B view. No problem. However, was looking at some dates in June (two bedroom) OKW, SSR and surprisingly VWL were available but both BCV and BWV were a total cut and paste. And as others have said HHI is so popular in the summer.
I have points at SSR. I have points at BWV. BWV is my favourite resort. But I'm not a planner and everyone is equal at 7 months. So this is a good balance. BWV points for when I can force myself to plan and for high demand times. And SSR for everything else...less than seven months out (which includes SSR stays!!!) Maybe you should consider a split like this.
Best of luck,
Lisa
