In the end our daughter agreed to let me sleep on an air-matress in her study, so I could go to the beach after our arrival and drive home the next day. That way it was only about 300 km each day.
Luckily the day was sunny - but freezing cold by an easterly wind. There were only dog keepers at the beach beside me, and two horses with riders. It was just great to breath the sea air, collect some mussels and watch the sea-gulls and many ships on the fjord.
It was strange to wake up in our daughter's place and to get breakfast made by her. She's not our little girl any longer, but a wonderful grown up woman.
