Hi Hans, I would think you would be able to get a bit of kip in the passenger lounge at the ferry terminal at Douglas,however, youre quite right the ferry does get in at the time you say, thats because its the "Fastcraft", if you go further up the coast to Heysham, which is next to Morecambe, there is a 02:15am sailing, which is the one I used to get, and its the "Convential" ferry (the slow boat lol) which usually gets there around about 06:00am,so you can get a bit of kip as you travel across.
