I had always purchased bus tickets a day in advance in Mexico. It ensures you get a cheaper rate and will be on the bus you want. I stupidly didn’t buy my ticket in advance for Bacalar. When I got to the ADO bus station at 10:30am the 11am bus I wanted was full. I’d have to wait for the 1pm bus meaning I’d waste my day waiting for and sitting on the bus.
I had two hours to kill before my bus and Campanella was down the street, so what did I do? Got ice cream at my favorite place one last time. Not the worst way to kill time.
