I find Grand Floridian rooms to be very thin walled and noisy -- if you have a loud neighbor. Same for VGF1, Royal Palm Club etc. So if they didn't rip down the walls and add sound insulation in between rooms, then they'll be the same thin wall noisy rooms they always were. It's fully dependent on your neighbors. I find BLT to be the quietest of all villas (as far as walls are concerned). SSR is pretty good as well.
