I had great expectations that were sadly not met. For the price of the room, I was expecting a LOT more for my buck, maybe I was just too optimistic. I will say the whole hotel was clean and didn't have any unsanitary conditions. But it just seemed outdate for the top price paid, it could use a spruce up. Our room was ready before posted check-in time and when we got to the room there were no problems. The wi-fi was free and the tv channel selections were pretty good. I would say this is an average hotel for amenities with a high price tag.
Usually when you pay top tier rates, I usually expect the service staff to be very friendly, didn't get that here, I think I had one of the service staff actually talk to me unsolicited. I would not revisit The Westin Convention Center.
My wife would probably give it 4 star just for the shower head, it was pretty amazing, but when that is the highlight, I don't think there is value here.
