Not sure what rooms some of these other reviewers had, but I stayed on the 6th floor of the North Tower and was happy. The large hallways showed a little age, but what you would expect for this price level. My room was clean, large granite bathroom was clean, had loads of towels, and the room was a roomy 400 square feet (approx). Free television.
The nightly entertainment in the nightclub lounge was very good all nights I stayed, and there was always a dance party going. Really good house cabernet wine.
Stayed in the North Tower more than once and I was equally happy each time. Ballys is in a better location, and has larger, cleaner rooms for the standard 2 beds, than many of its price equivalent competitors.
