No - both the park and rides are first come first served.
Mill Road, which is in the north of Brighton, fills up quickly. If you are coming down the A23, when you reach the roundabout at the end of the A23 dual carriageway, make sure you are in the right- hand lane. Take the third exit ( towards the petrol station) and go under a narrow bridge. This is Mill Rd.
If you are coming along the A27, you will need to come off at the Patcham interchange- follow the signs to Brighton/A23. This will bring you to the large roundabout, keep in the left lane, take the second exit and go under the narrow bridge. You will need to come this way, as you can only access Mill Rd from the bottom of the hill.
If Mill Rd is full - the residential areas of Westdene and Patcham, do not have any parking restrictions, so you could street park and walk to the park and ride.
When, Mill Rd is full, they will direct you to the racecourse, it should only take about 20mins but with all the football traffic, it will probably take at least half an hour.
