When we were at POP in Oct., we stayed on the 3rd floor ... nice and quiet. Nobody is above you, so you have no overhead noise (toilet flushing, showers running, etc.).
We stayed in the '90's (I think - the one w/the lap top icon). Our room was close to the lap top. Unfortunately, when we arrived at the hotel (at night) and walked to the room, it seemed like a long haul from the main lobby to the room. But, the next morning, we discovered that it was closer if we cut through the parking lot! Our area was very quiet and the one pool was close, convenient and much quieter than the hippy dippy pool (near 60's bldg).
I'd take the 90's again! We were very happy there!
