I frequent Vegas often and unfortunately this was the worst stay I've ever had. I had wanted to stay at Caesars for a long time and an impromptu trip and low nightly rates finally made that possible. I stayed in the Palace Tower and room was beautiful, bed super comfortable. The snack bar had an opened bag of cookies on it, so I called the front desk to make them aware so I wasn't charged. The customer service person I spoke with was friendly and made a note to the account. I was not feeling well from my travels (stomach stuff, not Covid) so I didn't get out and about for fun as I had planned. Instead, I went to bed early. Then, around 12:30 a.m. the neighbors in the connecting room next door starting getting loud, laughing, talking loudly and playing rap music. I could literally hear every word at most times. After an hour of hoping they would settle down or leave, I spoke to security who said they would send someone up. They never did. The party next door left for little over an hour and returned around 2:00 a.m. I woke up again and feeling just terrible, I called security again. They, again, said they would "be right up" to address the noisy neighbors, but never did. I even resorted to earplugs and pulled the covers over my head. Eventually, I got an hour sleep, but was awaken by laughter until they finally got quiet around 6:30 a.m. By that point, I had had enough, took a shower, and drove the 6 hours home.
