We went the Friday before Halloween 2005 (10-28-2005) and I think we arrived at around 11 am and picked up 6 tickets for our little party

We were the 1st wagon out that night but there were other wagons following us and when I say that I don't mean it was an endless procession of wagons. We had a space and I don't recall seeing any other wagons except at the loading area to know they had more then the 1 wagon. It might only be 2 going out alternating. I think we were at 7:30 pm? and I think they go till like 9? I think there is more info available and probably on the Dis main site.
It was very kewl. Nothing to scary because I can't stand haunted houses where people jump out and grab you, it's pretty kid friendly in that regard. It is dark. The storyteller has a lantern I think which is operated with one of those glow sticks. It is the "haunted hayride" so there is a surprise
You'd probably be safe to get tickets as long as your not arriving late that night but again I think they might have had some tickets still available and selling when we were waiting to depart. We went to the kennel to purchase our tickets during the day hours, I think we had to use the room key because they wouldn't take a credit card.
Have fun!!!! We really enjoyed our trip over that time period
I went and looked up the page...
