Ah, sunny Goodrington. I went to that exact same holiday park when I was a sprog.
Taunton is approx. one hour's drive from G'ton and probably a bit far out your way for a one-off knees-up, but there are a bunch of locals still pretty much into the R & R scene. Rock-a-billy stuff. Most of 'em even have the oldie white-wall tyres on their cars.
There's also a pub just off M5 junction 24 - they also congregate there.
By the by, I'm not sure if it's still there, but Goodrington had a neat boating pond the last time I looked.
Keep on keeping on, amigo.
