I'm an engineer and I like numbers, but DopeyBadger has me beat for compiling empiricle data and numbers.
That said.....When I did the half, it was right around 2.5 hours and that was with a few photo stops. Alice and the Hatter were just walking out to the teacups and I got that picture with no waiting. Buzz Lightyear took just a few minutes. Cinderella and the whole castle gang took a few minutes of waiting. My longest wait was for the all the Pirates of the Caribbean guys and the boat backstage. I think I waited a few minutes on that. For the full, I don't remember a ton of photo stops, but it looks like I did a few, and again, they were short stops.
I would like to do more photos this time around, but I still don't know if there is anyone I want/need a picture with so badly that I'll wait more than 5 or 6 minutes. If I remember to do so, I might hop off the course long enough to ride Rockin' Roller Coaster if I beg my way to the front. (Mile 22 split: 2.5 minutes!)
So at this point, I may have a half closer to 3 hours, and the full will probably be closer to 6, maybe 6.5 if I wind up in any Goof Troop type shenanigans.
I had pondered going for a PR on the 5K, but after Sunday's 6 mile run, I think I'll just pace myself for all 4 races, take pictures, have fun, and save the PRs for local races.
