Hi Carolyn,
You will have such a fantastic time!!! I'm excited for you!!
You have a variety of ages of kids and there is something for everyone.
If you can book a
character dining experience I would highly recommend that. It is such a fantastic experience and your kids will remember it for such a long time. There are so many fantastic dining options that your whole family will love.
Don't rush your way through the parks. Take your time and do the rides/attractions that you all are interested in. Another thing that my husband and I do is that I will take one or two of my kids and do something specific they want to do and my husband will do something with the other one (or two)
For your little ones (4yr/7yr) you will really want to do the character meet and greets--so pick up autograph books when you arrive!!
Make sure you pick up a Times Guide when you arrive to see all of the parade, show and firework times--those are must do's!
For your 7yr/11yr you can have them look at the Walt Disney World website and see what excites them or what there must-do's are.
Enjoy your resort--the pools at the resorts are so much fun--your kids will love that!
A trip to Downtown Disney is also a must do!
Make sure you take lots of pictures.
You will have such an incredible time!
Have a magical vacation!
Carrie
