As a bit of additional feedback, from someone that has only partially attended a couple of Fests:
A Denver Fest would be the most likely for me to attend at least part of, simply because I could pair it with a trip to visit family in the area as well. That said, I likely would only make it a long weekend on either end since I do have a limited amount of time off I can take, and I already have scheduled most of this year's allotment. Should it work, I'd either fly into/out of Denver or take the Zephyr to/from Iowa (where we also have family in the area.)
That said, even a Denver Fest wouldn't be a sure thing for me to be able to attend - the odds would probably be somewhere in the neighborhood of 50/50. I'd certainly push more to make that work, though, especially since I'd like to get out there anyways to visit family. Some sort of weekend (or Sunday/Monday) would be ideal, though that may not work as well for other attendees.
