Send us the flight number or the name of the boat and we will be there, whatever time it is, for nothing.
The late flight lands when the whole street is shut, and the harbour boat from the south arrives when it arrives rather than when the timetable says. Somebody is on call for both all night, and you will be let in rather than left ringing a bell.
Book the return leg when you book the room. We watch the flight you are on, because the domestic timetable here moves more than anybody visiting expects.
