I've volunteered to help with the Spokane bid (because, as much as I love the idea of making WorldCons cheaper, being stuck on Disney property with extremely limited food choices if one doesn't have a car is very no in my book.)

One of the things I'd love to address with the committee, should I get to interact with them beyond "hey, I got X pre-support and Y friends at Z Con," is the accessibility issue. One hotel is directly attached to the convention center, and the others are a 5-minute slow walk, according to the person I talked to. (Which, I gotta say, is a lot closer than most of the food in Chicago.)

Knowing my luck, I'll get sucked in to actually help if they win the bid. If I do, I'll poke them a lot about accessibility issues.
