I've stayed at Music twice now. At AoA twice now. The last time at AoA, I was in a LM room, ground level, facing the pool! I thought it was going to be a nightmare of noise. Nope, it was quiet as it could be.
I have also stayed at Pop at least 5 or 6 times now. No noise there either. I haven't found the values to be any noisier than any other resorts. I own DVC at both BLT and BWV....you can hear toilets flushing at all the resorts!!! I have yet to stay at a resort where that didn't happen. If it's going to bother you, just close the bathroom door.
My worst stay noise-wise? the Polynesian!!! We had a room that had a connecting door. While we were there, we had two different families staying in that connected room next to us. The first family wasn't too bad...a bit loud but we finally put a rolled up towel in between the two doors and that helped a lot. But...the second family was awful!!! Every night they had to call Gram and tell her all about their day!!!! Now, I have no problem checking in with the family. But really??? We knew every single thing that family did each day, everything they ate. I finally got right up beside the connecting door and said, very loudly...'Kate, please use your indoor voice. There are other people around us and they don't want to hear about your issues!!!' Understand, my dd Kate had done nothing. She was actually taking a shower at that moment. My comment seemed to do the trick. They were much quieter after that!!!!
