Determining interest of possible start/finish change

We have a chance to move the start/finish this year to Mississippi Natl golf course. This would allow us to avoid running through town for the finish and it would provide an on-site restaurant for after race refreshments.
First, would people take advantage of this and use the restaurant after the race ?
Second, if we use their lot as the start point, they have asked that any post race food or drink we have is purchased through them. Can we live with that, or is giving up that post race Surly beer too much to ask ?
It's important that if we use their lot, that we respect their wishes.
