My wife and I had lunch today at Damon's restaurant which is associated with the Clarion Hotel on St. Patricks Drive right off of Crain Highway.
I checked with a Manager at the hotel and received authorization to use part of the parking lot although I "promised" her that some of us would most likely visit Damon's since it is a football sunday. Whether or not that happens is not a concern to me at this point.
I think that it is the perfect spot since food, drink and bathrooms are just a short walk across the parking lot. I'll take a drive by there this Sunday afternoon to see if the area that I am looking at will have any cars in it since the skins are away this weekend.
In looking at the pictures the area that I am considering is the long line of spaces on the back side of the parking lot along the grass
