I know I have been to sold out concerts at Meadowbrook as recently as this month and must say that I am thoroughly impressed with their parking and traffic routing. Admittedly, its never been on a Holiday but we have always been out of the venue within 20-30 minutes of the end of the concert. I really don't think the traffic there in Gilford will be the big issue, more likely it will be Rtes 106, 3, & 93. I have always been lucky enough to get to my boat a mile away and stay on that for the night. Good luck.
