I am glad they don't hammer you because it's already such an expensive trip, if you have to travel and stay. If you want to add in a round or two of golf even moreso. Food and drink are good , very cheap and Merchandise is good quality.
a normal $60 a night hotel > minimum $250 a night. If you can find one. I booked mine almost a year out.
$40-$60 dollar green fee within an hour > easily $150-$250.
hard to get a good diner reservation.
I guess with 50,000 people a day descending on the smallish town that's to be expected.
