We are taking off tonight to Mexico City. How do we book these awesome tours? We want to do an archaeologic tour, we want to visit el temple mayor, and other historic sites. The hotel we are staying at is the Hampton Inn on El Centro Historico. Beautiful building. We want to visit the frida kalo house and museums. We just don't know if these tours need to be booked before we get there or if we show up and pay. Also, where do we go to exchange currency? We also want to visit the floating gardens (those cool boats). We tried doing an itinerary, but we don't know if some of the websites we found are legitimate or not. Our approach to this is going to the from desk when we check in and go from there. Are there any suggestions or recommendations? Thank you! :) we are so excited!!!
