The Goo Goo Dolls are the opening act for the entire North American Tour. You don't have to get to the arena early in the day. They usually don't even open the doors until around 6 p.m. The concerts usually start at 7:30 p.m. You have an assigned seat, but once the show starts you won't be sitting down.....you will be on your feet dancing, singing and screaming all night long. Once Bon Jovi came on, I didn't sit down once. Enjoy your first US concert. You're getting a great show.
