Caravan /resorts/anything for feb 1/2 term

[raspberrytart]

We have Feb 1/2 term off-hurrah and would like to get away-however we have ds(4)asd and would like indoor pools/soft/play but no boating/fishing lakes ,could probably manage small streams but anything deep a no-no. We live in Cumbria and dont mind heading north or south for 2-4 hours.
We have stayed in caravans before and that was fine,enclosed play areas are good and woodland walks also good. We have a tourer but thinking it might be too cold , if anyone has any ideas that would be great.
Thanks

Bumping for you as I also want to go away for half-term. Within a couple of hours of Bristol would be ideal for me. Got a weekend at Centreparcs in January, but half-term is a bit pricey.
