I love Surf's up - it was the first All-Star buidling and we stayed there the first month it was open!
The construction on the All-Stars and Pop appear to be similar. Based on my recent experience with being near the pool at the Pop, I would suggest staying on the opposite side, and it's not what you would expect. I could deal with the laughter from the people that were there, but the cast members and contractors that were working around the pool in the middle of the night were pretty loud. If you happen to wake up, you could hear them.
