Hello Elianys,
Welcome to the Disney Parks Moms Panel, and thank you for this excellent question.
Wishes nighttime spectacular is an unforgettable fireworks show in
Magic Kingdom Park that celebrates the power of believing. It is a moving and magical experience!
Wishes nighttime spectacular takes place on most nights, but not every night. Your best bet is to check the
Magic Kingdom Park calendar on the computer or on the
My Disney Experience mobile app. Simply use the calendar icon to find the dates you are interested in and check to see if Wishes nighttime spectacular will be taking place on those particular evenings. You can also find this information in the printed Times Guide that you can pick up as you enter Magic Kingdom Park. Just keep in mind that this is an outdoor show and subject to cancellation due to inclement weather.
I hope this helps with your planning, Elianys. Please stop back if you have any other questions about your upcoming visit!
Wishing you many magical memories,
Erin
