If parking in Lots 2-3, you need to pay $3 and put voucher on your dash. Recommend using coins or a credit card. The machine was very fussy about taking dollar bills. Some had a problem with credit cards also. Shuttle will wait for you.
I parked in Lot #8, which is in front of the lower level, Lohmann Theatre. Then I took the elevators up to the level of the Smithwick Theatre. And, on your exit, it is an easier out and onto the freeway.
