Sid and Bernie are sick of 'getting nowhere' with their girlfriends Joan and Anthea.
Camping is particularly good, as they all end up happily ever after.
The only negative thing I can say is that Jim Dale wasn't in it. I would rate it for Mature Audiences. There isn't a lot of nudity, but there are about five minutes of footage from a real nudist colony at the beginning. The producer, Peter Rogers did a brilliant job as usual. If you know, tell us who directed this movie, what other movies they directed, and whether it reminded you of any other movies you have seen.
