I'm sure there's two massive car parks within 5-10mins walk from the ground. I think ones called the Lonsdale carpark.
I used to park in it when I went on boozy weekends. It was around £10 for 24hrs. Its ideal for the sea front and ground. I imagine crowd will be small so easy get away.
We've booked into a B&B but it has very limited parking so no doubt be looking for somewhere to park for a couple of nights.
