That's good news RTS! Mapledurham's nice too - are you going to look round the old mill. Its fascinating.

English Jon - do you know Reading at all? Where would you be coming from? The festival is quite easy to find, but it depends how you come into Reading.
Caversham is the north part of Reading, on the north bank of the Thames. The festival is quite close the Caversham bridge. The address given on the leaflet is Thameside Promenade, Caversham Bridge, Reading.
The carpark is very close to the Holiday Inn hotel which is right next to the bridge.
There should be plenty of signs pointing the way once you get close. And once you are in Reading it should be easy to get someone to direct you to Caversham Bridge.
If you give me an idea which compass direction you'd be approaching from, and whether you'd be on the M4, A4 or what road then I can give you some more specific directions.
