If you want cheap entertainment, they have cosmic bingo on the weekends at midnight, games are $1 and it is a fun atmosphere. The bathroom situation is terrible inside the theater, so keep your ticket and there are bigger bathrooms just outside of the theater. It is small and every seat is a good seat, you really can't go wrong. Valet is now free, but please tip, they stand outside in MN winters no matter what! The theater is fantastic. Be prepared to get there really early and park far away, valet fills up quickly on show nights. Valet, slot attendants and bar servers are all very helpful and friendly.
They are constantly making improvements, adding more nonsmoking slots(it's very very smoky), changing the layouts, adding new slots. The rooms may not be updated but the casino floor has been. There is a pretty decent spa and pool area. I am curious to see what the renovations will bring.
Rooms are just average, you can hear everything going on in the hallways. While they may be 'regulated' they are way tighter than Vegas. I used to be a VIP and you could win jackpots every now and then and now you can't buy one. I have been coming here for a decade and it's not nearly as fun as it used to be.
