Places in Holland I have visited with my children, with lots of information on places we visited while away.
Travel To Holland
From the UK: Many airlines fly from the UK to many Amsterdam Airport. You also have the choice to drive to Holland (which is what we normally do). The Hull to Rotterdam ferry route is popular as is Harwich to Hook of Holland. Stena Line and P&O ferries cover these two routes. There should also the Newcastle to Amsterdam crossing too.
Travelling in Holland
Car: If you need to hire a car then you can hire one from the major airports or cities you are travelling to. Check out the car hire company for their pick up and drop off points. If taking your own car from the UK then remember to check what the local laws are and make sure your car has been serviced. Remember they drive on the right in Holland.
