Hi Elizabeth,
I love when I can save money on my Walt Disney World vacation!
In general, discounts are released between three and six months prior to the offer so guests have enough time to plan their vacation. The summer dates should be released soon as everyone is looking to plan these vacations. Make sure to look at
Disney Special Offer site as well as
Disney Parks Blogs and other social media sites such as Facebook and Twitter.
As for what can your three year old do besides Magic Kingdom-almost EVERYTHING! Walt Disney wanted families to experience the parks together. This is one reason there are very few extreme rides. My children's first visit to Walt Disney World included all four parks. The key is the order.
Visit Epcot on your first day. Journey through Spaceship Earth, explore the Living Seas, try Soarin' over California and drive a test car on Test Track. Then a trip around the World Showcase will have you visiting Vikings, having a siesta, visiting Japan and China and eating fish and chips in the United Kingdom.
Disney's Hollywood Studios has Disney Junior! Live on Stage and other great shows like Indiana Jones Stunt Spectacular and Toy Story Midway Mania.
Animal Kingdom is a safari and animal trekking in a beautiful park. If your little one likes dinosaurs, then he can dig for a dinosaur's bones.
At this age,
Blizzard Beach is a great water park. Tike's Peak is a great place to spend some time and there are many family rides.
Of course, no WDW vacation would be complete without a trip to Magic Kingdom.
Wishing you a magical vacation!
Beth
