The way I played stuff like this was to sit at the half way point in a Starbucks or something 2 hours away from being able to report. Call, and ask to be released. If they say yes, you’ll be at the game at your release time without pushing it at all.

Let’s say you have a 6pm release time. Call at 3:30. The will often say that you are released at 4 if you don’t hear from us.
