Does anyone know the title of a 1980's movie ?

Does anyone know the title of a 1980's movie about a girl who is about 11 years of age who's parents died and she went to live with her uncle. Her uncle owns a big hotel and the girl has her own room in the basement where she has everything a girl could want except for friends her own age. The girl goes around the hotel in roller skates. She is home schooled, until the end of the movie where she finally goes to school and meets people her own age. I have searched everywhere I could think of on the net, please help me!
