This was one of the most fun things we did while in Nashville. We had been to Nashville dozens of times, but we always seem to find new things to explore and this one was a blast. The workers on the bus were basically a DJ and a hype man who were great at their jobs. We were surrounded by bachelorette parties, but they were all definitely in a party mood which made for a fun atmosphere. They take music requests, there was an opportunity for a photo op by a sculpture at one point (as well as a pee break, if needed), there were drinking games, etc.
My only critiques would be that I would have liked to have heard a little something about WHY the place we stopped for photo ops was important to Nashville history/culture, and I was more under the impression this tractor was going to drive us around downtown in such a way we could take in the sites at the same time, but there wasn't much to look at on the route. Most times I looked out the window there was a lot of construction and not much else, so if you're expecting a "tour", you should look elsewhere. If you're looking for a kind of unique party/drinking kind of thing to do with friends or 21+ family though, this is a great choice, I'd say.
Oh, also from looking at the website, the person who booked our tickets was under the impression we would be riding around in an open space with a place to sit and take in the sites, perhaps. That was not the case. This was an enclosed area that felt more like a bus than a tractor. There were wooden bench seats on either side, but this is not the activity for you if you are looking to sit much. This is more of a dance bus, so basically you're paying for the atmosphere and unique opportunity, I guess. Again, I had a blast, so I'd still recommend it to party people.
