Hi Michelle,
You're a girl after my own heart as I too love nothing more than watching the days to my next Walt Disney World trip count down.
This information is actually still available to view in
My Disney Experience when it is accessed directly from the
Walt Disney World website (not the My Disney Experience app).
When you log into My Disney Experience from the Walt Disney World website, underneath where it says "Welcome, Michelle," you will see that it says "My Plans - __ days to go."
I'm not really sure why this information doesn't seem to be available in the My Disney Experience app but I have searched and searched, looking for it many times, but it simply doesn't seem to be there.
Wishing you a magical trip filled with memories which will last a lifetime!
Emma
