My eldest brother had a job working on a lighthouse off the coast somewhere many years ago, the only way on and off was by helicopter every day and he hates flying. He had to do all the crash training to go with it which was being thrown in the sea with a survival suit to get a real feel of what it would be like if the chopper went down. After one flight across he bought a sleeping bag, camping mat and some food the second day he told them he was staying in the lighthouse for the rest of the week because he was a quivering wreck on the helicopter, The next week he went prepared took his fishing rod and a load of food and lived in the lighthouse for the following three weeks when everyone else flew back everyday, apart from the flight there and back he said it was great
