My parents flew into town this morning and we drive out to Yosemite tomorrow.

Excitement is in the air!

I know it’s a bit late to ask, but does anyone have any hints or tips on how to best enjoy a short 4-day vacation near Yosemite?  Any spots we absolutely should not miss?  Any secluded and secret places in the park that we should hit up?  Any nearby towns with really weird museums or halls of fame?
