Ok, so the studio is on an Island and of course there is a bridge but you can only get over on foot. The car park is huge and there are no parking restrictions.
If you come to the Studio first I have a trolly for gear if required. The closest Mainline train is at HAMPTON Station , not to be confused with Hampton wick or Hampton Court. The station is a 15 minute walk.
The Road access is from Lower sunbury Road, so please make sure your sat nav does not take you to the wrong side of the river and West Molsey !
