There's Jungle mania in Bourne end ( just off the london road from high wycombe) activity world ( along the london road in high wycombe ) sports centre at high wycombe. Odds farm park, indoor and outdoor play areas, lovely day out, thats not far from high wycombe
we have been to wellplace zoo lemonice.To be honest its a bit tired looking now but its a nice cheap day out if you take a picinic,the cafe isn't up to much really. The play area isn't bad , the guinea pigs roaming free are really sweet and there is a parrot that says hello to you !
IIRC there is a Laserquest in Central Oxford (Gloucester Green near the bus station) that's about all I can think of ....... otherwise am I allowed to suggest looking on the netmums website as they are good for local listings?
