I wouldn't panic yet. I think that the PP was talking about booking a cash stay. Inventory for that is different than
DVC inventory. I think you will have a hard time getting the GV at BLT at 7 months, but getting a LV 2 bedroom should be okay if you call right at the 7 month mark.
I also believe that they just did the last BLT declaration into DVC which means the # of rooms available for cash guests has gotten lower and thus, not as many will be available for booking, including with discounts.
BLT is very popular resort and if now more than 90% of it is DVC inventory, it doesn't leave a lot for others.
