This afternoon I checked with the owner of Backline and everything is OK for Saturday from 10:00am.
The entrance is directly off the Station Car Park on the Farnham/Cathedral/University side, not the town side or for those with a compass, the west side.
If you are coming by train, take the exit for the University, not the town centre exit. This brings you out into Guildford Park Road. Turn left and turn left again down the slope signed Station Car Park/Farnham Road Car Park.
If you are coming by road and end up in the one-way system, you need to take the road signed A31 Farnham. Immediately after the railway bridge is a mini roudabout. Turn left into Guildford Park Road. Turn right into Station Car Park/Farnham Road Car Park.
At the bottom of the slope, turn right.
Just in front of the bridge on the right-hand side next to the advertising hoarding are some green gates.
This is the entrance to Backline.
This is the Station Car Park which Pay and Display.
If you carry on past Backline under the bridge you get to Farnham Road multi-storey car park which is pay-on-exit.
See you all there.
