Definitely go back
Only had a weekend in Mexico City so decided to take the Tourist Bus in order to get our bearings. Due to traffic the trip took about 4 hours but I really enjoyed passing some of the neighbourhoods and next time will now know which ones to stop over at - Coyocan and Condesa for sure. Spent Friday night to Sunday there and only spent approx. $200 AUD including museum entries, accommodation, food etc. Could spend weeks here and do something different every time, can't wait to go back!
Insider Tip:Tourist bus said it would take 2.5 hours for one loop but ended up taking 4 - Mexico City traffic changes everything so be flexible and don't work to a schedule too much. Eat where the locals eat for cheaper eats and more authentic food.
