Close to M4 for a group of us (from around the country) to meet up. Ideally indoor and outdoor places to sit and chat, picnic and cafe, playground. Possibly near Reading/Maidenhead/Windsor.
So far I have only come up with Bracknell science park but probably not so good to sit and chat if is raining but fine if weather is good.
The children range from 5 down to 1.
We are coming from Caridff, Oxford and London mostly.
