Hi Camille!
Unfortunately, Times Guides are only available once you have arrived at your Walt Disney World Resort hotel (it'll be located in your welcome folder at check-in), or at any of the theme parks.
According to the Disney's Hollywood Studios
calendar,
Fantasmic! is scheduled for the following dates/times during your vacation (when on calendar page click on
park hours on a date to bring up more detailed information):
March 13: 8 pm and 9:30 pm
March 15: 8:30 pm and 10 pm
March 16: 8:30 pm and 10 pm
March 19: 8:30 pm and 10 pm
For the most up-to-date information, make sure you pick up one of those Times Guides once you arrive to see if any show times have been added or changed. Also, when there are 2 showings of
Fantasmic! scheduled, the second one is usually less crowded.
Have a magical vacation!
Amanda
