There are a lot of things to factor into the decision - as you are seemingly aware.
if you leave the dome right after the end of the game with the masses of people - you will definitely wait at least 45 mins to an hour to get to the I-10 ramp. Sadly, it’s because the NOPD refuse to do contraflow around the Dome. So what ends up happening is people in the garage are trying to make left turns out of the portal, across 3 lanes of traffic to exit. As you can imagine - it can get to be congested mess.
If you leave at the 2 minute warning (obviously not ideal) - you’ll zip right out.
If you take your time exiting the Dome and hang out for a bit - you’ll find it will clear out enough to move pretty fast within 45 minutes or so. We typically wait out the congestion and just chill out. It’s really awesome on a fall afternoon - especially when we win. 😉
I love my parking pass. I love knowing I have a reserved space that is safe and somewhat secure from theft and vandalism.
I recommend it!
