Ah bugger, just noticed i have posted 2 threads of the same, can a mod merge them please.
Given where we live the kids are used to sitting in the car for hours on end, so distance is not a massive issue but i think 14hrs to cornwall night be too far for the pair of them.
Trekster, we really like the lakes, went last year and must admit its very handy for us with plenty to do. As for centre parc's, we have been to whinfell a few times (admittedly pre kids)and although it was very good it was always let down by the rubbish food.
Never visited the moors or devon, will give then a look see once i get onto a computer and off this stupid phone.
