We also just got back from GF, and while there were definitely people at the pool, the rest of the resort was definitely a ghost town! I don't think we saw a single other soul in the villas! We did a split stay between Riviera and VGF, and Riviera seemed pretty busy (lobby was always bustling). Grand Floridian was a nice change of pace!
Parks felt crowded at times, but waits were nonexistent. The longest we waited the entire trip was 16 minutes for Flight of Passage, and we did all the big rides at MK, HS, and AK.
