Galleria Questions

A store inside the Galleria is doing a popular product release Saturday morning and I am interested in starting a line (or joining in one if I’m too late), but I have a few questions on how to accomplish that.

1) Are you able to get inside the Galleria after it closes to sit outside the store? I know the hotel elevators access it. 2) If I can’t get inside, is the best place to line up at the front door or at a door near the store? What will be opened first you think? 3) Can you park overnight in one of the Galleria lots?

Never tried something like this at a mall, so any help is appreciated. Cheers!
