Do you have to make a reservation or can you do a walk in or both?

You can either walk in or call and make a reservation

Both

It does not matter you can walk in or make your reservation

You can do both

You can do both if you don't mind waiting you just show up for golf if you want if you call ahead to schedule a time and the place upper or lower deck

Both however it is the holidays so if you're traveling I'd call ahead
