You don't necessarily have to drive. Formby is right next door to Freshfields station and West Lancs adjacent to Hall Road. Going by train adds a little atmosphere.
If, by some freak, all the courses mentioned are fully booked there is also a part-links in Southport, Hesketh, and Ormskirk is probably the best of the inland courses in this part of Lancashire - the back nine is Harold Hilton, compact and tight, while the front nine is newer and on a much more expansive scale.
