Independence Hall

Sure is

My fellow guides are correct, about 25-30 mins. Stop by the desk at the visitor's center and grab some timed tickets, you may also want to allow yourself some time to take the tours of the Liberty Center as well as explore the many other buildings that are within the Independence Hall system. You can literally spend hours between all the different buildings that are also open and available to take in. The old statehouse is but one in the system.

Yes

West wing congressional hall. The docent said it might be dark in the hall. However no flash lights were not necessary for me, probably because I went early on a sunny afternoon.

Yes there is a parking garage. You do have to pay to park though.

We went after 4p and did not need tickets. Groups of 70 were let in every 40 minutes. Be prepared to stand approximately one hour before you make it in.

Yes. It's a nice store in the visitors center. The same building you pick up tickets for the tour

A visit will more than answer that question. The United States is a nation and an idea that evolves with every challenge we overcome. Go gor a visit and you'll get a better perspective of why it was built. Please note our beginnings were humble and fraught with the specter of failure.

The building is free to enter but I don't recall them having an original copy of the document here.

They are free, but you need to show up early I the day or reserve ahead for tour tickets. They only give out so many per day, and once they're out they're done. Lot of school field trips during the week and a lot of tourists on the weekend, so they do go fast.

You can get free tickets at Independence Visitors Center.
