How much time someone usually spends there?

My kids are older so we spent maybe 5 minutes wandering around the small ghost town photo ops. The shop had a lot of rocks which my kids like so they spent about 10 minutes picking out geodes and then another 5 minutes breaking them open. The panning for gold, shells, gems, is overpriced. You pick the package you want and then an employee pours the bag contents into your pan to shift through. My kids did not like this but they had been to an actual panning site before. Little kids who were doing it loved it though because they were guaranteed to get the treasures from the bag they chose. Depending on how busy the place is maybe 30 minutes max? They only allow 8 people in the store at a time so there could be wait.

It's a pretty small shop with a good amount to look at, if you do buy something you'd look to spend at least 30-45 minutes here
