Stayed in Bally's just a few times in my life, unless you count when my family went to the MGM Grand in the late '70s and early '80s (fortunately not during the 1980 fire), which later became Bally's.
The first time was a sort of staycation in the mid-2000s. Wasn't even my room. Was at some party in a suite there with my then-girlfriend, which ended around 2am. Everyone went home, including the people who rented the suite. They were going to check and go back to their place, but my girlfriend asked if we could just hang there and check out on their behalf in the morning, and they said no problem. So she and I were left alone there for the night. We didn't need the room because I lived just down the street, but might as well use it because it was already paid for, and she was good friends with the person who got the room, so they trusted us.
Seemed fun until I tried to go to sleep and the traffic noise on Flamingo was brutal.
Second time I stayed there was in the 2010s during WSOP. One of the times I got a comped suite. The others I got a regular room. I made sure to ask for "the non-Flamingo side" each time, and itw as much better. Not a great place, but not bad. I did radio from there a few times. I was going to spend some time there during the 2021 WSOP, but I ended up cancelling those dates, and instead only went for the Main, where I stayed at the Rio.
Anyway, if you go to Bally's, make sure not to get a room hanging over Flamingo, or you'll be hating life.
