been there many times and never dissappointed, if you search the forum you will find numourous recommendations.
Pay for the campsite and you get unlimited access to the theme park and access to the swimming complex at certain times during the day, no swimming complex like it in the UK. All only a short drive from the Hook of Holland.
We were thinking of going to Duinrell next year. Have you booked the whole package sailing from Newcastle through Keycamp? I have looked on their website and can't find a sailing from Newcastle.
I got the brochure has all the sailings in it. Just watch your costings, the price of the ferry and cabins is only 1 way, We've booked 2x3 berth cabins to keep the cost down, Hubby and 2 kids in 1 cabin and me and the other 2 in the other cabin. BTW also got the Eurocamp brochure and they work out more expensive.
