How long does it take to go through the entire museum?

You can take as long as you want. 2 to 4 hours usually.

I took me two hours for the first part. If you have to read everything, you'll need two days, so i paid double to have the year long membership.

I would suggest 2 to 4 hours if you look and read the displays. It's a wonderful experience - well worth the time investment.

School trip there lasted about 2 hours. We could have spent more time there.

It took me and my son about hour but we rushed it

We only left ourselves an hour, not enough time to take it all in, give yourself 2 hours at least

It depends on how much you read and look at. If you want to see the original Washington tent, you have to sit in a theatre and listen to a short lecture. We looked at everything and spoke with the curator about the water color of Washington's camp they recently purchased. We were there for 3-4 hours. The museum is actually pretty small as museum go. An average run through can take 1 1/2 hours. I like to linger and absorb.

Depends on how long you linger. I would plan for 2 hours and adjust based on your interes level.

It's self guided

Around 2-4 hours depending on your personal pace.

We took 2.5 hours.
