Hi, we are planning a trip in mexico after spending a week at the beach. We will rent a car, drive to Guadalajara for 3 days, then have reserved a B@B in Guanajuato on December 26-28. We are a family of 5, and the youngest is 7. I realize it is not much time for seeing all of it and would appreciate your input on how to spend the couple of days that we do have there. Also what kind of weather should we expect? Thanks a lot!
