I've been looking forward to writing this post for a few years. We (wife and 2 daughters) just added 295 points at VGF, which gives us a total of 1,095 points!!

We have 800 at BLT and 295 at VGF. Still want to add about 200 at BLT and enough for a 2-bedroom at the Poly when it opens. But we are set for now.
BLT is our favorite and has sentimental value to us, so we stay there most of the time. We do stays in 1BR, 2BR, GV, and even studios. Just depends on the trip and what else we are doing (and whether family is joining us). We have also used our BLT points to stay a few nights at other resorts, like BWV, WL, and AKV. I really enjoy the boardwalk view at BWV and the Savannah view at AKL, but the contracts do not last as long and we always gravitate back to the monorail line.
VGF purchase was a bit of a surprise for us. I have been to WDW at least 150 times in my life, but I had never stayed at the Grand Floridian. Visited the model, and the rooms look amazing! I actually prefer modern designs, but the VGF rooms are polished, comfortable, and will provide a nice change of pace. We stayed at the hotel for a night to get familiar with the grounds and make sure we would like it. One stop to the MK is a real plus.
We bought a fixed week for a 1BR standard view in week #46 (the week before Thanksgiving). Since Thanksgiving moves every year to the fourth Thursday of the month, week #46 will always be the full week before Thanksgiving. We really enjoy that week because of the lower crowds and Christmas decorations.

With that being said, we will probably only use the fixed week ocassionally. We love that the fixed weeks gives us the flexibility to opt out, and those points are sufficient to get a 2BR standard view 2 out of every 3 years. Now I just need to add on at the Poly....
