We became members at BCV in April, and this was an issue for us b/c we immediately wanted to plan a trip that included a GV for our big party. We have a 10 day trip in November.
We became members INSIDE of 7 months of our trip. It was way harder for me to get a 2 BR at BCV then a GV elsewhere. EVERY GRAND VILLA WAS AVAILABLE for the dates I was looking. Some were available for 8+ nights. We only needed 4, and booked at AKV. This is Nov 10-20th, and we are staying the 11-15th in a GV. First night we are in a 2 BR at AKV, and the last 5 nights we are in a 2 BR at BCV. The 2 BR at BCV was WAY harder to book.
I had my pick of GV's. My understanding is that this is not a crazy time to go, but the weekend we booked is the last for F&W, Veterans day and the end of Jersey week. Because of F&W, I was especially shocked when they told me the BWV GV was available for all my nights.
We also just returned from a last minute trip, Aug 24-29th. When I called, to book in mid-July (only 6 weeks out) there was a GV at SSR and OKW available. There was a GV available at BWV for 2 of the nights. I asked just to be curious, we didn't need to book one.
So for what it's worth, my first two trips---both booked inside of 7 months---showed GV availability.
