I think if your not in the main mini run, then you have to use the car parks in town. there are quite a few.
Cheers for the reply thanks will do ill tell my dad as he had no a clue ?

There are quite afew car parks within Brighton, Normally NCP i believe.
They do tend to be rather expensive so be prepared to pay alot.
There are also alot of parking restrictions within brighton and most residential areas are double yellow lined or require a permit to park.
In the past friends of mine have parked outside brighton and jumped on the bus down to the seafront, not only is this cheaper but you also don get stuck in all the traffic when trying to leave.
