Hi Jaime!
Congratulations on your first Walt Disney World vacation.
Those are great ages to visit Disney. Still, due to the age difference between the girl and the boys you will probably need to plan for the group to split some times. This will be perfect when the older boys want to ride thrill rides and when the girl wants to meet and great princess or enjoy a makeover at the Bibbidi Bobbidi Boutique.
The Pirates League is an experience that all 4 children can experience together - and the parents as well.
This is a really fun activity to share as a family.
Character dining and Signature dining are a must during my family's vacation.
Advance dining reservations are highly recommended - up to 180 days in advance.
Visit each theme park for a full day and if possible revisit Magic Kingdom once or twice.
Early park hours, late hours as well, usually have the lowest crowd levels and best weather of the day.
Bringing your own stroller allows kids to rest at any time and help carrying all the bags through the parks.
To make the most of your time, try getting familiar with the
parks and attractions before arriving.
Thank you for visiting and letting us help you plan a magical Disney vacation.
Hope to hear again from you.
Miguel
