We stayed at BLT prior to our DVC purchase. We were frequent GF guests, and the idea of being able to walk to the park was enticing! We also have friends who bought at BLT and we figured it'd be an easy sell. Boy were we wrong.
The studio felt restrictive and cold, not Disney at all. The hotel itself was more like.. well, a regular hotel, not a Disney resort. If you wanted to do anything other than walk to the park, the trip was longer than it seemed to be at any other deluxe resort, even staying at an outlying building. We ended up stuck there because of Hurricane Sandy, and ended up staying an extra night before they said we couldn't stay for our last night and made us move (luckily just over to the contemporary). No one ever occupied our room, which was just an annoyance overall. We loved getting a chance to stay in the Contemporary, and BLT felt so much less seeing what the attached hotel had to offer.
Last trip we decided to give DVC one last chance and toured the VGF. It was as close (if not closer) to the main building/Monorail/Gaspies as any of the other buildings, the rooms were spacious and stunning, and the theming was spot on. We never felt like the rooms were 'less' than those of the GF like we did for BLT. We bought on the spot.
Just a different POV. Unfortunately there may be a waiting list at VGF right now - my BIL just bought at the Poly because he didn't want to wait for VGF.
