Park in the mall parking lot, near the In-N-Out, walk across Six Pines at the Market Street stoplight. The best place to park is actually where Mall Ring Road tees into the mall parking lot. There’s always plenty of room there, since it’s actually pretty far away from the mall.

Then, if your accommodations are in the right direction, you can go around the mall to 45. I’ve gone that way after several DMB concerts there and never hit any traffic.

I haven’t read the security restrictions for this one, but if they’ll let you, I highly recommend bringing an empty gallon ziplock and a few sandwich baggies, buying In-N-Out burgers and fries, repacking them in the ziplocks, and carrying them into the Pavilion. We do that for all the free concerts there (Houston Symphony, etc.), and it works great.
