Hey Lesley!
Your ability to make
FastPass+ selections are as close as your smartphone or laptop computer. Using your
My Disney Experience account you can make and/or change all of your
FastPass+ selections on the fly right from your resort room. With all resort and theme parks equipped with Wifi, you should have no problem connecting while on Walt Disney World property.
If you haven't already, you can
download the free app to your smartphone. This is a handy tool in your trip planning as you will always have the ability to make changes to your plan right at the tip of your fingers.
I hope this helps with your planning. If you have any other questions about
Disney's FastPass+ service or any other aspect of your Walt Disney World vacation please come back and see me.
Wishing you a
*MAGICAL* vacation and a pixie-dusted day!
