We had issues with the temp in our room (rm 254), we got in, mid-afternoon, and it was set at 70, & reading at 80°. We turned it down to 65, thinking it would need time to cool off, we left for a few hrs, came back to the same 80° room. I went to the front desk because the phone didn't work, she asked what room I was in & she said she would send someone up. I got to the room & about 2 mins later, something kicked off, it must have been the ac, and it started cooling down, few mins later, the guy showed up at our door to look at it, not sure he did anything as it was already cooling down, but he was very nice & let us know he was there till 11, if we had any more issues. We spent the night listening to this thing kick on & off, even till we ended up checking out the next day. It was a loud banging, and it looked like, in the room, that a portion of the wall was removed & a large metal panel was attached to the wall, and every time it kicked off, we heard it constantly bang. I could've gone and asked to be switched to a different room, but it would have been a hassle, and we just needed sleep!
