couldn't get in any of the nicer restaurants to eat - paid for strip view got a pool view - flight was cancelled so we had to drive 2 hours to another airport only to arrive the following day called reservations and told them but we still got charged for the night we weren't even there. Defiantly not coming back. we spent at least $10k as we do every year.

The employees were AMAZING! I came in contact with TRISTAN, IVAN, LISA IN HOUSEKEEPING, THE LOVELY MAN THAT LISA SENT TO MY ROOM WITH LINENS, ETC. The parking was excellent and FREE! The security guards were super helpful on each encounteer and made going to the parking structure feel more safe to do. The options to eat need to be helped out a bit as there are very few options and they close super early. The rooms were horribly outdated with seating (2 overstuffed chairs and 1 desk chair) extremely dirty/stained with who knows what. My socks became so dirty from the room carpet that I left them behind to be thrown in the garbage. They have two EV charging stations (1 for Tesla and 1 for non Tesla EV's) at the far end of the parking structure. The hotel needs an update everywhere except for the casino which is overall pretty good. If it wasn't for the Manilow concert held there I would not stay there again.
