I just got two emails for the shows at Gillette. One, which came in reference to our GA tickets that we are not using, was direct from Gillette Stadium. The lots are opening at 3 PM for parking/tailgating. The email states that police will be turning away anyone that arrives earlier. You might be able to park in one of the Route One lots I mentioned if you want/need to get there earlier, not sure. This email also states that GA wristbands will be distributed beginning at 5 PM and they are not allowing a wristband line to form prior to 3 PM.
The other email, which came from U2 RedZone, says people will have access to pick up Red Zone tickets from the gate starting at noon the day of the show. There's also a pickup window the day prior, which is interesting. I thought we had to get them the day of the show.
