Introducing ' super cama', the first class of the Argentinian long-haul buses. Seats convert into flat beds, meals and drinks are served and DVDs are played. It's so much fun, we didn't want to get off after our 18-hour trip from Buenos Aires to Puerto Iguazu. Best of all, it's only marginally dearer than a normal, run-of-the-mill coach, meaning we can squeeze a little luxury into our hostel-dwelling, backpack-hauling, bread-eating existence.
Fergie, eat your heart out!
