There was a similar thread but I didn't want to butt into someone else's thread. I am looking at Aeromexico flights with a 12 hour daytime layover (approx 8am to 8pm). I figure with an hour for immigration and getting back to the airport 3 hours early (Amex or Aeromexico lounges, plus departure immigration if necessary) that would still give me a full day in Mexico City for approximately 9a-5p.

The other thread indicates we'll need to collect luggage so I'm thinking a private tour with car and driver would make sense; leave the luggage in the car while seeing the sights. Are these sorts of tours available, and does anyone have a recommendation for finding them if so? Obviously Tripadvisor is available to us but a recommended itinerary would be welcome! I have plenty of time to learn but as of now I don't really know anything about the city.
