If you drive, Eccles, drive down to the sea front (facing the Pier), turn right, about 100yds along you'll see a big hotel called The Thistle. Get into the right hand lane (it feels like you're in the middle of the road), and turn right immediately after The Thistle, so you basically go down the side of The Thistle. When you turn into that side road, in front of you and over to the right you'll see the entrance to an underground car park (opposite Jamie Oliver's on the left side of the road).
It's worth using that car park, because it brings you out right in the middle of The Lanes, and close to the sea front.
