I agree with all of the others comments, eating out is expensive with a family of 4, so best be prepared and self-cater where possible. We have had two great breaks at Center Parcs, although it's expensive to book and yes you do have to book well in advance, it's worth registering with the site and then you receive details of their offers. It's worth taking your children out of school for the saving you can make. My final comments are be prepared, book well in advance, take your own bikes and plenty of food, and have lots of fun, fun, fun!!
