I remember very little about it, but it came into my head tonight and it's driving me nuts.

What I DO remember is that there was this girl who had to impersonate a princess, and she was getting trained to behave like one. She was blonde, in a blue dress, and she was made to balance things like books and teacups on her head. That's nearly all I remember, beyond knowing she had a bangup success convincing everyone she was royalty.

Anybody remember it and know the name?

Sounds to me like you are referring to "Anastasia"?

Anastasia (1997)

No, definitely not Anastasia. (I've practically got that one memorized.) The one I'm remembering is years older, and it's meant for really young kids. The animation is simpler too. Thanks though.

I think it is Carebears: Adventure in Wonderland (1985)

OMG! THat's it! Thank you so much!
