Our very kind host at our Playa del Carmen Airbnb delivered us to the ADO bus station, and within moments Aaron and I were on a nice, large tour bus headed for Cancun. I have forgotten the exact cost, but I'm pretty sure that the 2-hour nonstop excursion to the airport didn't run more than $8 US per person.
At the airport, we had a small issue. Apparently when we paid the 500 pesos per person to enter Mexico a couple of weeks before, they had issued us paperwork that we were supposed to keep. I distinctly remember throwing it away, since I didn't want to carry around more stuff than I needed. Well, it turns out that it was needed.
Next time, I'll pay more attention. We had to fill out the same forms again, which wasn't a huge deal. What was kind of a bigger deal was that we had to pay 500 pesos each again. Thankfully, I still had that much cash on me, but it was a bummer to part with around $60 US unnecessarily.
I nearly went crazy on a family mid-air after one of their children spit on me (she was trying to spit on her brother... but still... ugh). Unfortunately, we had to go through customs and security in Miami, even though we were headed back out of the U.S. again. Aaron told me to run ahead because he had gate checked his guitar and would have to wait for it to be unloaded. I understood that he would meet me at customs. I waited and waited, but never saw him. Finally, after becoming certain I must have missed him and even more certain that I was about to miss the flight to Saint-Martin, I went on through and ran like a track star to the gate. He hadn't been able to find me and had headed on there to wait. Our flight was a bit delayed, so all was well and I had a few moments to compose myself again.
