Yes
I know alot of the tour bus line's start and end at 5th and market. Go to the visitors center at 6th and market street across from independence hall and ask a parks employee about this or call the bus line you wish to use. :)
bus drops off at visitor center and then walk over
Call and ask.
Not sure about this. Best thing I recommend is calling center to ask.
