If you've never vacationed anywhere but Disney, DEFINITELY go somewhere else! Preferably somewhere without a theme park!
We love Disney, too, but there is a great, big, wonderful world out there, and Disney is only one teeny tiny part of it.
I'm not sure what your family is into or how old your kids are, if you have any. But here are a few suggestions:
-New Orleans--explore the French Quarter, take a ghost tour, take a mule-drawn carriage ride, go to Audubon Park to see the zoo, marvel at the grand houses of the Garden District, ride the streetcar, learn how Mardi Gras floats are built at Mardi Gras World, get out of town and take an airboat tour through the swamp, eat yourself silly with delicious food
-Washington D.C.--visits to all monuments and the Smithsonian Museums are FREE! Explore them all! See Charles Lindberg's plane and the Apollo 11 at the Air and Space Museum, see the pandas at the National Zoo, see Dorothy's ruby slippers and the original Star-Spangled Banner at the Museum of American History (they even have one of the original Dumbo ride vehicles from
Disneyland!), see a show at the Kennedy Center
-St. Augustine--explore the Castillo de San Marcos, browse through the shops in the Old City, see all the oddities at the Ripley's Believe it or Not museum, learn about pirates at the Pirate and Treasure museum, go to the beach, drink from the Fountain of Youth
Those are just a few examples! Get out there and explore!
