Greetings Ghost Fans,
Today when you purchase your tickets for Disney Theme Parks, you pay one fee and can visit any attraction as many times as you would like. Prior to the early 1980's, you actually paid an entrance fee and bought Ticket Books. These tickets marked A through E, allowed you into attractions with an A through E rating. Haunted Mansion was an E ticket due to its high popularity.
At Disneyland, guests were prompted about the attraction using one E-Ticket to enter via a sign. At Walt Disney World however, in addition to a sign, guests were also told via an unseen voice that they would need to remove their E-Ticket from their booklet for entrance.
This mysterious voice eminated above the heads of those about to enter the stone colonade in front of the house. This was, of course, long before the addition of the front gates, the toppled fountain and hearse. Why, even the green canopy was not there at the time.
This speaker is still in its original location where it isn't seen well from the queue area. If you stand near the hearse you can see it slightly, but the best viewing is from the Liberty Belle Riverboat.
