So this new update answered some questions for me. I was thinking of getting to DHS at 7:30/7:45 (park closes at 8) and go see Osborne Lights. Thought I'd meander a bit and slowly make my way out and to the entrance by 9.
hmmmm, think, think (done in my best Winnie impression)
I made dinner reservations at 50s prime time for 750pm..i figured this solved the problem of what to do for the hour from when the park closes to the tsm event
