So, I returned to Cancan on the afternoon of the 15th, and left the next day. I took both first class and second class busses. But, they are both still very reasonably priced. The first class busses have on-board movies, reclinging seats, air conditioning and bathrooms. The second class busses are less well equipped and make many more stops.
Entry is free on Sundays.
I had a few problems on the trip. I neglected to bring an original copy of my birth certificate on the flight. Continental Airlines did not get my luggage transfered on my connecting flight to Cancun at the Houston Airport. I did not get my bag of clothes until the 10th in Piste. They did send them along to where I was staying there.
