If my show starts at 9pm, what's an advised time to get to the arena?

I'd get there about an hour early. There's plenty of parking garages within a few blocks.

I would say get there for 8:15. Lines typically move quick, so I don't think you need to be there a whole hour before. Hope this helps!

1 hr before will get you there at a good time.

they usually start letting people in one hour before , so around 8.

There will be traffic once you are in DC, and parking is a headache

Around 8

Get there around 8p
