I have been trying to find out the name to a movie I watched back in the late 70's early 80's... it's about a boy and a girl who run away and end up spending a few nights in a museum... that's about all I remember other than while they were at the museum , the would collect money from the fountain at night and wake early before the museum would open and leave. They slept in the bed at the museums . What is that name? Can anyone help me . Its been driving me nuts for almost 10 years now.

It's based on a book.
That is the best book ever.
You should read it.

Love, love, LOVE that book! Quinn nailed it!
