Shanly,
Absolutely right. Don't try to do it all - you won't be able to!
Instead focus on enjoying your time in the
Magic Kingdom. Let the girls look at the attractions and entertainment of the park on the Walt Disney World website and pick out what is on their "Must Do!" lists. Compile them all together, and then plan out what you will focus on seeing.
Make sure that the adults get to pick some rides too. Remember, with the Rider Swap program you can have fun as well!
I would also plan one solid meal in the immediate area. Maybe a character meal (
Chef Mickey's,
Cinderella's Royal Table), a more upscale dining experience (
California Grill,
Narcoossee's), or something approachable and fun for the whole family (
Whispering Canyon Cafe,
'Ohana).
I am glad to offer more specific guidance if you give me an idea of what you are looking to do, and what kind of time you have to work with. Just send me a follow-up question by going to my bio page on the site.
Have a magical vacation!
