I have not stayed at the Clarion but I do know that it is one of the stops on the C bus that the ART runs. The C bus runs between the Radisson, Coast,Hilton and Clarion on it's daily run to DL. It's a quick route. This doesn't help much but just thought I 'd throw it in.
I got the Radisson for $54 on Expedia and we were there just last weekend. It is a full service hotel and their breakfast buffet is quick and delicious. They have a concierge for tickets, a restaurant, gift shop, heated pool, etc. The staff there is terrific and I don't think I would stay anywhere else. The rooms are nice too! Loved it.
PS Only drawback is that parking is $10 a day. I was able to get a rental car on Priceline for only $12 a days so it was cheaper and easier to rent a car than to take the bus/shuttle even with the parking fee (we were only there 2 nights however).
