Good advise. Just one clarification...The museum is free with the
AirVenture admission, and it's also free with an EAA membership at any time.

One trick I often use is to park across from the museum and take the bus
to show center. It's easier than the other large lots. The only
problem I encountered was that the busses don't run through the end of
the Theater in the Woods presentations. I learned not to park there,
especially if a huge monsoon that dumps 5" of rain is expected because
it's a long walk, and from that much rain, your stuff won't dry out for
a week. (Voice of experience.)

Your ticket will get you through the Museum (or it used to) which
takes a good two to three hours. Easily three if you take the time to
really look and it is worth doing.
