The Crowne Plaza Valley Forge was so noisy I didn't get two hours of connected sleep. Their "quiet zone" rooms weren't quiet. They had a wild party downstairs. I asked for a floor on a higher level and away from guests that might make noise. They put me on a floor with a group traveling for a special event. They met in the hallway and were organizing their itinerary outside in the hallway at 7am. They were knocking on doors loudly to make sure everyone was up, etc.
Doors were slamming all night long. Partygoers were on both sides of my room singing and yelling. The parking lot had more people playing loud music. I went to this hotel because of an on-line recommendation. I'd never do it again.
