If you're looking to do Vegas on the cheap with 4-5 people, this is THE hotel to stay at. For the price you pay (my friend had a free room, but I remember the rates being maybe around $60 a night? Def cheaper than $100), the room is really big for what you get. The beds aren't that comfortable but who goes to Vegas to sleep? The bathroom is clean and there is plenty of space for multiple suitcases lying out without tripping over them. The room is clean and the inside of the hotel is a bit outdated, but not nasty or janky :)
Also, the location of Bally's is great! It's connected to Paris and is in a pretty central location on the strip.
