I'm trying to find the name of a fairly old movie. It was in 80s or early 90s. The parents of a three siblings were leaving for vacation and someone had to work and support the family. They were tossing a pizza carton and the older sister had to work. Then she was preparing a fake resume and got herself a good paying job in a serious company. She was taking money from her little safe in her room and not replacing it for awhile. At the end, she was throwing a party at her house where her parents came early from vacation and she had to confess that she was a liar. That's all I know. Can you help me?

I am pretty sure it is Don't Tell Mom the Babysitter's Dead.
