And yet the fact that they didn't need elevators for the Haunted Mansion stretch rooms meant that they weren't even operating that first scene for paying customers on my last visit to Walt Disney World. They just had both doors open on each side of the stretch room and the line just snaked right through there and straight on to the loading area, which was in full view just as soon as you entered the house.
I was amazed that they would stoop so low! It got worse when I returned to the Magic Kingdom Park two days later and they were still doing the exact same thing, so it obviously wasn't just a temporary one day only thing.
If both of the stretch rooms don't work, or you don't want to spend the labor to run them and staff the extra CM's, then just shut the ride down. It was a really tacky stunt in my opinion and cemented in my mind the fact that WDW and Disneyland have very different priorities when it comes to operating their signature E Ticket attractions.
It didn't help that once I went on WDW's Haunted Mansion it was in the most pathetic shape I've ever seen a Haunted Mansion be in. Tokyo has an exact duplicate of the WDW version and theirs was stunningly maintained and looked like it had just opened the week before, even though it is a 24 year old ride.
