There will be no problem with finding a stuffed animal to fall in love with....the marketing folks at WDW are diabolical geniuses!! There is a huge selection at World of Disney at DTD, but as pp mentioned, there is pretty much the same stuff everywhere.
My son picked up a stuffed Animal (muppet character) and my daughter has started a collection of stuffed character "babies"..the disney character is a baby and wrapped in a blanket! These are really cute and plentiful...if you are not careful, she will want every one, so just keep her focused for 1 or 2 favorite characters. Many rides also exit via gift shops and you often have to walk through hotel gift shops to refill your drink mugs.
