I picked up a copy of the Club's 'Continental Caravanning' brochure at the NEC yesterday. Looking at the descriptions of the various sites I find pitches described as EL, SP, SO, PR and probably others. So what do these mean? I have searched through the
brochure for an explanatory guide, but without success. Can anyone point me to the place where I can crack this code? Please?
