Which Haven sites do you reccommend?

GPark

We've been doing the sun holidays twice a year for the last few years, and last year tried Haven for the first time. My 4 yr old ds loved it he loves the characters, the kids clubs and the shows in the evenings.

We have tried a few different Havens so far, found Devon Cliffs and Kiln Park too big/busy, loved Littlesea but think Weymouth will be too busy this year (work commitments mean we need to go in July). So I'm on the hunt for a new Haven park to try.

Would ideally like one of the quieter, less busy sites as my 18 month old ds will probably be following his brother around and wanting to get involved - we've just returned from Doniford Bay which was quiet enough for ds2 to follow ds1 onto the dance floor in the evenings without me worrying about him getting knocked over by older children, and we were able to sit close enough to the dance floor to allow them to get involved without us hovering over them all the time.

So can anyone recommend a Haven site suitable for a 4 year old and a 1 year old, that's not going to be as big/busy as Devon Cliffs but is within 3 hours drive of South Wales?

Any suggestions would be great
