It seems like once you've played one slot at Charles Town, you've pretty much played them all. The other thing about slots: Update your machines! MGM has amazing machines! Wizard of Oz, a lot of Willie Wonkas - machines with super fun bonuses. I want to be entertained for a couple of hours and I can't do that if the slot machines swallow all of my money in the first half-hour. Look, I don't mind if casinos take my money, I expect it - but I want to have a good time. I always end up winning SOMETHING at MGM - at Charles Town you will lose $100 in 15 minutes in a slot machine.
I've been gambling here a lot and am just going to make the switch to MGM in DC.
