just spot checking prices, they are more, but they aren't terrible. you are definitely paying a premium for the extras. i guess you get what you pay for. for example the "major" at Pinehurst is $600 for 36 holes with one of them on the #2 course. obviously more than standard greens fees, but not a lot more and you get the tourney atmosphere. so it comes down to if the experience and "tour treatment" is worth it to you.
also, you get a 10% discount to golf galaxy. not sure if there are limitations, but i'm looking for a new set of irons. so i could get a good portion of the membership cost back with the discount.
