I have seen a few posts recently about Duinrell & Efteling , both of which I am desperate to visit!
However we are north of Glasgow so flying seems the best option. I know there is a ferry from Hull which I wouldnt completely rule out, however driving for more than an hour or two with the kids is torture 
We are a famiy of 5 and looking at the travel once there getting to Duinrell seems easy however I think you would need a car to then get to Efteling ? Is anyone able to give any advice who has done this?
Our 3 DC are still all in car seats so hiring a car over there and taking our own seats is putting me off.
