A:
We bought our tickets at the bus station days before the bus trip over the Andes. We were able to get the exact seats that we wanted. We had come from Santiago to Mendoza on Andesmar, but were not impressed. The attendant was rude and did not seem to like his job at all. The trip was supposed to be 8 hours, but the traffic over the mountains was good and the time at Customs & Immigration was only an hour, so the entire trip was about 7 hours with no stops or chance to get food. The only thing we got was a cookie and coffee/tea about 30 minutes after departure! Take snacks or a sandwich! We are traveling by Cata tomorrow to Santiago from Mendoza, so hope they will be better. And we are bringing food!
