Our room was above the gym, but we didn't know this. When we heard these very loud sounds that actually rumbled our room, we complained. The Front Desk that evening claimed they couldn't figure out what the sounds could be. They recommenced at 5am in the morning but this time as I listened over and over I thought I recognized the sound. At check-out later that morning, when I complained again about the sound starting up again, the front desk clerk knew immediately that I was hearing the weights being dropped. What a disappointment that a hotel that was charging a small fortune would be so disingenuous in their response.
