The ILs like us to go on holiday with them every summer. We have DS5 who is indoorsy and dd2 who is outdoorsy. The holidays are invariably rubbish with a bunch of people with different agendas and no one capable of making a decision!
Anyway, ils have heard from colleagues that centreparcs is the way forward. I'm not entirely convinced because a, it's expensive b, it'll be crowded peak season and c, my son will hate most of it!
However, I am open to be proved wrong, if it's awesome! Are there any alternatives (preferably in the south UK), that you can suggest?
