We own at BLT, but I was wanting to switch to VB at my 7 month mark so I could get a beach cottage. The beach cottage wasn't available for our entire stay nor were the rooms we'd need (there are 18 of us in all). I called on Monday (our 7 month mark) to switch, and when VB wasn't available, I was able to switch our dedicated LV to a MK view. We also already had a 2 bedroom lockoff SV, but I didn't change that one.
Anyhow, after thinking about it for a couple of days, I stressed myself out about the number of points the MK view was taking, so I called back this morning, and I was able to switch back to a LV with no problem. However, I didn't realize how all of the points were being allocated when I switched (we had banked points as well as VB points in our account), and the lady that made the change said I would get back some banked points and 52 VB points. I told her I didn't want my VB points back because they have to be used first. Apparently, since I had two reservations, they used current points for my 2 bedroom lockoff and used banked and VB to book my LV/MK view room and couldn't change that. ?? To make a long story short, we switched my reservation back to MK view before the call was over with no problem because I knew we wouldn't use the VB points before they'd expire anyhow.
My point in all of this? I would think you should have pretty good luck for mid-August at the 7 month mark depending on what type of room you're looking for. I've done a whole lot of switching views in the last few days at BLT with no problem. Hope this helps.
