Trying to find an older movie title
I am trying to find the name of a movie my grandparents and I used to watch together. It is about a late teenage girl who's stepmother and sisters treat her like a maid similar to Cinderella she runs away and ends up at a country club location. At the country club a family has gathered to celebrate the grandmother 90th? Birthday it becomes a family runion type gathering. The Young girl pretends to be a reletive that was suppose to arrive later that weekend, she falls in love with one of the cousins in the family and really become a loved member of the group. Towards the end there is a big hot air balloon sceen that ends up the whole family in a nudist colony illegally and they all end up in jail. In the end the step family finds and reveles the real cousin and expose the girl as an imposter. The step family tries to send the girl off on the plane.
If anyone knows the name of this movie which I last recall seeing in the early 90's please let me know this was a beloved show my grandparents and I used to watch together during my visits to their house and now both of them have passed on and I would like to share this movie with my child.
