Make sure you schedule for a specific time, i forget if that's done through Groupon or if you have to call. But otherwise, yes, just show up.
Are children allowed on the tours? I have two 9 year old boys that would like the underground or the gangster tour.
I did the same thing when we went. You have to schedule the tour through American legacy's website. At checkout, you enter the voucher's code from your Groupon in the discount box.
I'm not sure because my tour was in Newport. I also used Groupon but I believe I printed something, it should tell you. If not sure call Legacy Tours.
