Hello Nathalia and welcome to the Disney Parks Moms Panel.
I'm so happy to know you're bringing both your beautiful boys to visit the magic of Walt Disney World Resort this coming August as part of your darling 4 year olds birthday celebrations. Oh boy! I can just imagine how excited you all must be as you count down the last few remaining days.
You've made an awesome choice by deciding to spend your son's special day at the
Magic Kingdom Park as I think it would be perfect for both he and his older brother. The Magic Kingdom Park is my favourite place in the whole wide world and I would say your boys would love to experience almost
all of the Attractions, but I believe they'd especially like Buzz Lightyear's Space Ranger Spin, Big Thunder Mountain Railroad and the Seven Dwarfs Mine Train.
Utilising
FastPass+ can really enhance your Disney day and should allow more time to have fun with your family instead of standing in line. At present Guests may make 3 initial
FastPass+ selections each day for 1 Disney Theme Park and after those are depleted can make further selections via a
FastPass+ Kiosk. I'm sure you've done this already, but prior to making those all important
FastPass+ selections you'll need to create a
My Disney Experience account and then link up your Disney Theme Park Tickets to it; this will then enable
FastPass+. Have a great Disney day ~ Jane
