We liked Centre Parcs, but for me the ultimate holiday is always beach, pool, big hotel with buffet breakfast and several different restaurants. In some ways you can get that vibe at Centre Parcs but I like the Far East. What can I say, I'm just a sucker for long haul and tropical nights....sadly budget is now more tents and bucket and spade!
In an ideal world you would take your child to the kind of places you like.....then they will grow up liking the same stuff you do and you can all be happy together. Well that's my ideal world anyway. My children do like soft play places which I find ! But all of them like swimming which is great .
Any holiday helps enormously with ds's language and behaviour.
we are on 'tight' budget, so anything other than cheap is out anyway, but best thing we have found is devon cliffs holiday park at exmouth. we use Newmans holidays to book (they are private owners organisation even though it is a haven camp) that way we can book specific caravan to meet needs, they have beach on site, lovely pool and not too busy (unlike Butlins which is always heaving!) they also have good quiet adventure playground and are only 5 mins drive from exmouth beach which is huge and (usually) quiet. Suits both dh (physical disabilities) and ds (ASD and LD).
