I was lucky enough to stay in the North Tower which was fine. I haven't been to the South Tower, so I can't comment on those rooms.
I tried to get a room close to my friends since we were here for the same wedding. I came in pretty late, but the front desk person was pretty accommodating. She found me a room on the same floor, but looked sad as all they had were junior suites which would be an upgrade fee. So for three nights, the cost was 56 bucks. Total. For a suite with a fridge and a lot more space than a normal room. I was fine with that. I went through Priceline anyway, so I got a pretty good deal that I already paid for.
The room had nice enough beds, but they seemed a little small for queens. The room was clean, the bathroom was clean and the shower had water pressure. I was pretty happy about that.
Bally's is connected to the Paris so basically you have access to the same stuff as the Paris for a lot less. I was fine with that. Lots of restaurants on the way to the Paris that are tasty and I've reviewed them
There is also a food court downstairs on the pool level that includes pizza, hot dogs and stuff that kids and adults would like.
The Casino is a bit smokey for my taste, but Vegas is pretty smokey.
Tip. No resort fees. I know that sounds lame, but those add up. Remember that with any of the Harrah's properties.
Tip#2. There are better buffets than the one at the Bally's.
Bally's is close to a lot of places on the Strip so it makes it a very good location for the price.
I would recommend here if you tend to do more than just stay in your room or your casino.
