If we're day guests trying to make rope drop, and the lots don't open until 1 hour before park opening (ie, 30 mins before the first admissions), it doesn't seem like there is a ton of room for error. Any pointers as far as which lot/garage is best, whether we should worry about shuttles running at that hour, etc? We're coming from the south if it matters. As two adults we can move fast, but will definitely have at least one small backpack so will need to be checked at security. Thanks!
