Are there seats or benches throughout the museum for older people to rest during their tour.

Yes

I'm with Robert. There is some outdoor and indoor seating. Note that, when I was there in Oct 2018, one of the outdoor seats was rusting and I wouldnt trust it. Throughout the walk there is no seating, but its short, maybe 100 yards around before you're looped back to the entrance with seating.

Yes there are benches throughout but not in every room. I like to sit down and wished for a few more seats

It is relatively small and I do remember there being some places to sit throughout.

I agree with Robert. The museum as a whole is not overly large. So hopefully the aged ones would be ok. I also don't remember about seats on the walk-through. Enjoy!

There is a sitting area in the first section of the walk through. The museum itself isn't huge, though. I don't remember there being seating set up throughout the walk.
