Thank you Mark, all good to know. Wife gets the "mal de mer" just from swimming in a swimming pool, so the boys can take the car and trailer on the ferry while she comes on a plane.

About bringing partners and significant others, I was thinking more about things to keep them and the kids occupied with while we enjoy ourselves?
Staying in a hotel sounds expensive. A camping with cabins usually is more affordable, and acceptable for the family. Biking up to 10km's is OK, or arranging transportation otherwise. Would be best to stay close to the rest of the gang tough!

About the wind.. I suppose the lows bring a nice supply of wind with them, but do you get thermals on sunny days? Land and sea configuration looks like there should be a nice breeze during sunny days? Just trying to convince myself that the sailing will be good..

Oh, and driving on the left side of the road looks positively dangerous. Every time I try it, drivers coming the other way go bananas with their horn and headlights. I am certain it must be something wrong about it.. I know the police are very much against mixing drinking habits with driving, but it might explain why you insist on driving on the left side :-)
