I have decided I am too old for overnight ferry trips (Brindisi in Italy to Igoumenitsa in Greece) that spit you out at 4.30 am. That was after a night sleeping across 3 very hard seats ("reserved seats") in the half-lit cinema of the ferry, with a baby crying and doors banging all night. Only 2 functioning toilets for the entire deck. But we did get some sleep, we survived and lived to tell the tale.
