MK is good since she can ride almost everything. We took both our DDs just before their lst birthdays. We did everything in Fantasyland except Snow White (and Philharmagic was not there at the time). Dumbo was and still remains their fave! You can do the Riverboat, Aladdin, Buzz Lightyear, you name it. Bascially we avioded the rollar coasters and naything that was a thrill ride in nature. Anything slow and cute will fit the bill. Try the teacups, just don't spin it.
Also, if she can sit, try Belle's storytime. it is really nice.
