Hi!
I've been to Cancun/Tulum before, but I've never flown into Mexico City (ever) and then flown to Cancun before heading back home to Austin. I've been researching MEX and the layout, but I'm wondering about immigration papers and the like. What should I expect doing a domestic flight within Mexico? When I arrive in MEX will there be any papers I will need to retain in order to fly to CUN? Same question flying from CUN back to Austin? I have a tendency to throw things away.
What is the best way to get currency? Last year in Tulum I took dollars assuming I could use it and a credit card and learned that I got jipped with my cash and no place took cards. I'm reluctant to carry a wad of dollars over with me this time. I know to take a credit card and do a cash advance, but where is the best place to do that in the airport? How much is a reasonable amount to take out for 3 days of exploring and eating - roughly?
I know the rules about getting a legit taxi to the hotel from MEX, but what is the best way to get back to the airport? I think Uber is an option, right? I'm always a little worried about not having something scheduled, especially if my phone goes wonky like it did last year in Tulum. Has anyone used the shuttles? Does getting there 2 hours before the flight, like in the US, make sense?
Finally, any other random advice regarding being safe, what not to eat, as well as things to do in Mexico City would be appreciated. Tulum is going to be spent laying on the beach and getting sunburnt, so I'm good there. ;)
Thanks, y'all!
