Just been in touch with a lad I know (Watford Supporter) and he's given me a bit of parking advice.
Thought it might be worth sharing:


Hi

Not sure if i will go, lately I watch at the Pub becasue with 4 fans in the house it s getting expensive.
I would give yourself a bit of time and park in The Avenue Car Park (The Avenue WD17 3NU is nearly it for your satnav)
The Carpark is in the middle of a roundabout and cheap .
Over the road from the carpark is the town centre and you will see a large pedestrian subway you need to go under that subway (Horns Pub one side of the road library the other side) and walk down the high street. Eventually you will get to Market Street turn into that road (On your right) go down over traffic lights and at the end of the road turn left and simply follow the crowd.

Have a good day and I hope we keep up our winning streak

Cheers
