We are still trying to decide on where to stay. We are going in September 2013. Have to decide soon which week since some of our group have to pick vacation for work. We are trying to decide between the week of 9/21 or 9/28. It looks as though the week of 9/21 is cheaper at Ballys and the week of 9/28 is cheaper at Flamingo. Are one of these weeks better than the other? We have stayed at both and like both. Concerned about all of the construction....thanks!
