I only found out about this movie recently, and managed to download for viewing.
The premise was predictable, having being used in other movies before however, the idea of a nudist camp definitely was different.
The story followed the expected line, and ended with the expected conclusion but, on it's travels, it was rather enjoyable, and very unexpected. In places, it was quiet funny.
The only thing that slightly spoiled was, the late introduction of naturism etiquette. I've never been to a nudist camp yet, I am aware that members are obliged to carry a towel at all times.
The two reasons are very simple. For new male members, it is to cover up expected unwanted displays until the mind and body adjusts, and for all members to place on seats or other areas where they would sit, for hygiene reasons.
I was 2 years old when this was made so, it's possible the towel etiquette came out sometime after, I was much older when I read about it.
A quirky movie that is not quiet as smutty as some might think, and the granddaughter and aunt characters would espouse this, as the movie progresses.
A rather enjoyable view, and I did manage to see the uncut version.
