We stayed here for one night on 10/13.
I paid for a "Park King", and was put in a large room with a living room and separate king bedroom, with a really cool plasma screen tv that rotated in the wall to be usable in either room. (I'm easily impressed, ok?

) The bathroom was awesome, with one of those "no curtain" rain showers and an immense tub.
A bottle of nice cabernet was waiting for us on arrival, complete with a wine bag if we wanted to take it home - which I felt was a simple but very nice touch!
We ordered a late and very simple room service Friday night - and it was perhaps the most expensive soup and fruit I've ever had in my 42 years. Still, the service was fast and the food was good.
We didn't receive breakfast coupons. I was up early and went to the restaurant to buy a cup of coffee. They looked up my room number and gave it to me at no charge. When we went to breakfast, we ordered from the menu. When I asked the server about the Diamond breakfast benefit, she said "It took off $10.00 apiece". A little chincy, I thought, but the food was excellent, and the service was outstanding, so I figured I'd check with the front desk.
At checkout, the front desk agent said, "Let me just adjust your restaurant charges off your bill, since you're a diamond", and proceeded to remove our whole breakfast bill.
Our stay was short, but I felt that I received everything I would hope to receive as a Diamond. We both agreed that this is a cool hotel and would return again.
