Check out this clip of the Kiss Goodnight from Magic Kingdom. If you have never heard of this, it is unannounced and usually takes place anywhere from 15-40 AFTER park hours. This is a way to help let guests know it’s time to leave as some may have entered a ride prior to park closing and then exit the ride technically after park hours end for the night. If you get a chance to stay for it, it truly does wrap up your day at Magic Kingdom in a special way.
