"We were given a room near the elevator. We didn't notice anything that evening because we were out quite late but it woke us up at 5:30am. First it was once every few minutes, then every minute or so, then eventually it was constant until check out. Sounded like a jet taking off. If you stay here make sure you are a long way away from the elevator! When I informed the front desk upon check out I was told I would be compensated with Hilton Honor points. I have yet to see them."
