Hi Justine,
The Electrical Water Pageant takes place nightly and usually follows the schedule detailed below:-
Disney's Polynesian Resort - 9pm
Disney's Grand Floridian Resort & Spa - 9.15pm
Disney's Wilderness Lodge Resort - 9.35pm
Disney's Fort Wilderness Resort & Campground - 9.45pm
Disney's Contemporary Resort - 10.05pm
Magic Kingdom - 10.20pm (only during extended park hours)
(When Wishes Nighttime Spectacular is scheduled to take place at 9pm, the Electrical Water Pageant runs approximately 10 - 20 minutes later)
Please bear in mind that times are subject to change without notice and inclement weather can cause cancellation of the pageant.
As your dining reservation at Whispering Canyon Cafe is at 7.25pm, you will have plenty of time to enjoy your meal before the Electrical Water Pageant begins. The best place to view the pageant is from the Beach which you will find just behind the swimming pool.
Wishing you a magical trip filled with memories which will last a lifetime!
