holiday in wales,devon or cornwall

[notanidea]

need recommendations for a self catering holiday with good activites for 9 year old and 2 year old.I hae left it late but we can only go last wek of july.

Helpful Holidays have some lovely places in Devon and Cornwall, and often seem to have late-ish availability.
www.helpfulholidays.com Some have pools, and many have play equipment in the garden, or a games room with table tennis etc.

Not stayed at this particular park, but recently stayed at their Winchelsea Beach park in Sussex. I checked and they still have availability last week in July if you're up for this kind of holiday...?
