If I were you, I'd look on Pinterest.
You could do different props or flower themes that gave to a nod to each movie, but also make the centerpieces similar in how you put them together - something that unifies the themes from table to table, if that makes sense.
Snow White - a basket of apples centered on a wood tree circle/tray
Winnie the Pooh - really pretty jars of honey centered on a wood tree circle/tray
Beauty & the Beast - the red rose under the glass centered on a wood tree circle/tray
Peter Pan - a lantern w/ some pirate coins centered on a wood tree circle/tray
Alice & Wonderland - a large teacup w/ some hearts playing cards centered on a wood tree circle/tray
Toy Story - toy soldiers "hidden" in a plant centered on a wood tree circle/tray
Tangled - a floating lantern sitting in a cast iron skillet centered on a wood tree circle/tray
Cinderella - a glass slipper on a pillow centered on a wood tree circle/tray
Or, instead of the wood circle, you could do silver trays. Small votive candles at each table around the "main" centerpiece would be pretty too.
You could also find a nice set of Disney storybooks & include the appropriate book w/ each centerpiece.
