Our trip is about a month away, and we are deciding what to do on our last day in Tokyo. We really have just one day open, so we are wondering whether it is worth it to do a 1-day tour. Anyone have any experience with this? We were looking at JTB tours or the tour through Viator? If I were traveling solo, I wouldn't sign up for a tour, but as I'm with my mom, I was wondering if its worth it. Do the tour guides give you a ton more information? It would also help with possible confusion of navigating the city.
