Is there bus parking near the museum?

Yes there were 4 or 5 buses there the day we went

There is a lot nearby. Have to cross the street to get there

There is also Bus drop off on the side of the building. Mostly for school buses, but I see those there all the time.

Yes in lot nearby

Not a designated bus parking but buses do park in a nearby parking lot.

Yes. I believe thee is a big lot across the street
