I own both AKV and HHI. Once my trip happens this summer, I will have stayed at all the DVC at WDW till Poly opens.
We had no problem get part of our trip at GFV this summer at 7 months, but had to change the dates. Waitlisted its so we are doing a split stay at BWV and GRV booked less than 7 months out.
2 years in a row we did christmas week booking at 2-3 months out. 2012 was just one night at BLT, 2013 was 5 nights in a 2 bedroom at SSR.
