My husband and I are going on an overnight bus to Mendoza soon. I've never been on a bus for this length of time before (14 hours?!) and just wanted some advice from seasoned bus travelers. Any essentials that we should bring? Blankets and pillows? We're going Cama Suite... so would that be provided? Are there power outlets on the bus? Anything out of the ordinary that you can think of that we should have in our carry on luggage? Any other tips for getting through a long buss ride?
