Also I brought these online today

Solar powered fan that will run overnight too.. will be jamming this in the ceiling

some 3W Led Lights for:
Red one for a night light for the kids inside cabin
2 red ones for under the galley in the evening
2 white ones, unsure why
Some LED Dimmers, just in case:

Some Puck Lights

(they are only 2W but 3 should give enough light
Also 1m LED Strip (wharm white) for the galley.
Thats electronics sorted except 3 USB ports (2 in cabin and one in galley)
They will all be 12V with the plan to buy a solar panel for xmas,
