For what its worth I always go patron, becasue I am risk averse. NF will sell out this year. For RoSfest, I buy regular seats because there are always plenty available. For both fests there is not a bad seat in the house (except maybe the last row of the balcony
)
Worse case: If patron tix are too expensive and you get shut out at the box office, there are always people that buy tickets and are unable to go as the show gets closer. Every year I have seen tickets go on sale as the show approaches either on progressive ears (
www.progressiveears.com) or on the NF forum.
Good Luck!
