We're heading to Camp Bestival (nr Lulworth) with friends and will be getting to the general area much earlier than them so looking for some ideas for the morning so Country Parks / small attractions. Kids are 6 and 9 and we need to fill from about 10ish until 2ish so need food too 
We're coming in on the A31 through the New Forest I think so anything on that side would be good and don't want to get too close...
Any recommendations?!
