I suppose it all depends if you’re interested in history. For me it was one of the most boring days of my life (just my personal opinion) but I went along with it because the group I was with wanted to do it. It was a long hot day, and we got eaten alive by mosquitoes. Maybe you could find out some more information about a meal included and such as that if one person is concerned about food. I’m assuming food is included since the tour is so long.
Again, it’s just my opinion, I’m sure a lot of people find this tour very interesting.
