I agree.
I gotta admit that even when I visited Gettysburg as a kid, I thought that the place had a lot of cheesy tourist trappy stuff.
I mean, I get why all of the stuff is there.
My dad taught high school throughout the school year and he worked for the Commonwealth of Pennsylvania every summer. One year, his summer employer sent him to the Gettysburg area for a week of training. My parents took our pop-up camper to a private campground in Gettsyburg for that week of training, and took us kids (four of us at that time) for a family trip. I was a teenager, and I was the oldest. My mom had to find activities to keep all four of us kids occupied for that whole week. We swam in the campground pool. We toured the battlefield and the Eisenhower farm. However, we also went miniature golfing. We went to that wax museum where the wax President Lincoln recited the Gettysburg Address at the very end of the museum tour. We did a bunch of cheesy tourist stuff.
I was amazed by how many souvenir stands I saw in Gettysburg.
(Funny, on that trip, we didn't go up in the tower. I bet that my mom thought that it was too expensive for the entire family to visit. We did go to the Cyclorama, but I am pretty sure that the Cyclorama had free admission back then.)
