We have a family of 5 and own at VGF. I love that I can fit my family in any room available at that resort (studio, 1 bed, 2 bed, GV) so if I'm short on points one year, we can opt for a studio. The first trip we did a split stay - 3 days in a 1 bed followed by 4 days in a studio. After seeing the space in a 1 bedroom, with a king size bed with a locking door for privacy, my husband told me to "buy more points". We now stay in a 2 bed and often invite grandparents to stay with us. Although we don't own at BLT, I LOVE VGF! I can happily hang out at the pool, or hand in the lobby of the hotel listening to music. I love the that the feature pool is just steps from the Villas and right next to the beach. Since this pool is doing a refurb, we tried the other pool and found that we love that pool too! Great pool bars at both as well! We also love the quick service at Grand Floridian as well as the wonderful restaurants and it's a quick walk to Poly for Dole Whips and Trader Sams as well as their great restaurants too! We added on points at BCV to have an Epcot resort but we only fit into a 2 bedroom at that resort which limits options. Although I like the BCV pool, I like the Grand Floridian restaurants and lobby more and the views are much better too! And I've only stayed standard view at VGF. I'm considering selling my BCV points to add more at VGF....

I love the food options at BLT but don't love the theme there (or lack of one) so we opted against buying there (but we have usually seen availability at 7 months there for the times of the year we travel). Resale value was important to me too - I wanted smaller resorts because I thought they might hold their value a bit better if demand was greater. (However demand will be good for either of the options you choose so you can't go wrong with either). Good luck with your decision!
