Frustrated butcher Fred Ramsden and his dim electrician friend Ernie Bragg happily head off for a holiday trip at the Riverside Caravan Site, while their respective wives Sylvia and Vera look forward to their health farm holiday. Once at the caravan site of Major Leap, Fred starts making eyes at two young female campers, Carol and Sandra. However, as Ernie talks in his sleep and any infidelities are likely to be spoken of in the marital bed after their holiday, Fred is despondent. Professor Roland Crump teams with Roman expert Anna Vrooshka in an archaeological dig at the site. Arthur Upmore and his wife Linda are saddled with her mother Daphne and her vulgar mynah bird. Arthur is caught in a compromising position with attractive blonde Norma Baxter whose husband Joe is lumbered with their giant Irish wolfhound.
After a few drinks with the amused pub landlord, Fred and Ernie discover that the caravan site is riddled with excavation holes. Daphne is perturbed by the discovery that her estranged husband Henry Barnes lives a downtrodden life as the camp's odd-job man, despite having won the pools. Major Leap is determined to give the place a boost and arranges an evening cabaret for the caravanners, but a mix-up over the phone secures a stripper, Veronica, rather than the singer he wanted. Carol and Sandra having hooked up with archaeology students Bob and Clive, Fred and Ernie pick up Maureen and Sally, two beautiful young women from the village. Some wet paint, some glue, heavy rain that causes the tunnels of the dig to collapse, and the arrival of their wives soon bring their planned night of passion to a halt.
Casting
The main roles are played by Carry On regulars Kenneth Williams, Bernard Bresslaw, Peter Butterworth, Joan Sims, Kenneth Connor, Jack Douglas and Patsy Rowlands. Newcomers to the series in major roles are Windsor Davies and Elke Sommer. Sims played the role of Rowlands's mother, despite being only eight months older than her on-screen daughter.
Supporting roles are played by Sherrie Hewson, Carol Hawkins, Ian Lavender, Adrienne Posta, George Layton, Larry Dann, Larry Martyn and David Lodge. These supporting players were mostly recognisable comedy actors at the time, but not long-term regular members of the Carry On team. Liz Fraser had appeared in three early films in the series; her re-appearance here was after a gap of twelve years.
Filming
Chilly spring filming meant the bare trees, muddy fields and icy breath are all quite visible, although the setting is a summer caravanning holiday. A similar dilemma met the cast and crew in Carry On Camping. The signage in Fred Ramsden's butcher's shop clearly shows that the shop is closing for the Easter holidays, which can occur as early as March.
In 2023, actor Larry Dann dedicated a chapter of his autobiography "Oh, What A Lovely Memoir" to share his memories of the making of this production.[4]
