Yeah- PR nightmare, hadn't put it into that perspective. This will be my first trip in the continental US without a vehicle. Giving up that type of control has me moderately freaked out. I am excited for the whole not having to drive thing, but lack of control is not my thing. Everything I read says buses run about an hour after park closure, then there is the 45 minute lines to get on the buses, hanging back behind those crowds when leaving the park, etc. Mathematically I wasn't able to wrap my head around the time constrainsts of all that. Thanks though for talking me off the ledge.
