Long time lurker, first time poster ...
We are Pop frequents (20+ stays over the last 12 years). We just returned home from a 9 day stay 3/29-4/6.
We have never experienced any issues with noise until this last trip. We were in room 3216 in the 50's lakeview, a connecting room to 3217 which my parents occupied. You'd think that was the noise issue...NOPE! It was coming from the other side of the wall in 3215 which my sister and her family occupied! I didn't complain, naturally, since it was my own family but that is the first and only time I've ever noticed hearing noise from my neighbors during any of our stays - I could hear laughing, drawers closing, toilets flushing and other "biological" noises... This was our first stay in a refurbished room so I'm not sure if it's a coincidence, or the noise was better buffered when the rooms were carpeted.
So for those asking about noise, YMMV.
