Hey Christina!
Disney's FastPass+ service is a great way to take the stress out of any Walt Disney World vacation. I found on some recent trips while there were
FastPass+ selections left almost every day, they were for attractions which are historically less crowded such as Living with the Land, It's A Small World and the Seas with Nemo & Friends.
FastPass+ selections for headline attractions such as Seven Dwarfs Mine Train, meet & greet with Anna & Elsa and Test Track were typically gone very early.
There are a few of ways to experience those headliner attractions if you are willing to get up early. The first is to make your way to one of the
FastPass+ kiosks to make your selections for the day. You can also head straight to the ride you (they) would like to experience the most. Lastly, you can use your My Disney Experience account to make your selections either the night before or morning of your trip to the parks.
With little ones, however, I would suggest
buying your tickets now and
linking them to your My Disney Experience account so that you can make your
FastPass+ selections as soon as possible. Not only will this guarantee that your kids will be able to experience some of their favorite attractions, it will help you reduce the stress of long lines.
I hope this helps with your planning. If you have any more 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!
