in March 2016, I got back to my roots and took a short solo trip to Mexico City. flights are eminently affordable from most US airports, and the city is conveniently in the same time zone as Central US. I went alone as a female traveler and had only one moment, on one evening when I stayed out later than planned, in which I worried about personal safety.
the basics: most US mobile carriers now treat calls / texts / data in Mexico as if they were domestic, which makes it seamless to stay in touch with family and friends on the cheap. you can easily get pesos out of almost any ATM, or opt to exchange cash (I recommend ATMs where possible, because bank rates are usually more favorable and my bank [hey First Republic!] does not charge on the currency exchange AND refunds all ATM transaction fees). the metro system takes you pretty much everywhere, and I highly recommend it for any traveler who wants to actually experience Mexico, and not just bop around in overly air-conditioned tourist vehicles.
I spent my days exploring the city and eating plenty of food. I forget where I stayed – I’m sure it was fine and cheap – and honestly, I forget which exact museums and historical sites I visited. they were gorgeous inside and out, easily accessible by public transit, and affordable to visit. I probably just followed Wikitravel’s advice. if you’re still a student, BRING YOUR STUDENT ID and get that discount!
one thing I tragically missed out on was the Blue House, aka Frida Kahlo Museum. I couldn’t get the website to work with my US credit card… I even went to the museum and tried to buy a day-of ticket, but the line was too long and I was anxious about getting to the airport in time. it’s a priority for my next trip.
handful of food recommendations, always important: tostadas on the street [got mine outside of the cathedral]. tacos al pastor, with nopales aka cactus. so good. just look out for them on the street, I got mine also from a street vendor. pozole, a yummy and not-too-hot soup, from the Internet-famous Casa de Toño. overpriced but yummy ice cream during my failed Blue House trip, courtesy of Nómada.
it’s a good idea to know some Spanish before you go. if all else fails, pull out your phone and Google Translate live. especially if you want delicious, cheap street food, you’re not going to get by with English alone. drink bottled water and be merry!
