As you may know, Rea and I ran the Star Wars 5K at Walt Disney World in Orlando earlier this year. It was an absolute blast. I have a total love/hate relationship with running... but let's not get into that. This is, after all, the Disney section of the blog.
If you are going to WDW for a race, I suggest you book at the All Star Resorts. They are inexpensive (for Disney) and the transportation to and from the races are unmatched. Yes, Disney does offer "better" hotel selections with race transportation, but (according to my sister) the buses don't run as frequently to the other resorts. That might not seem like a big deal until it's 4 in the morning and you are waiting around for a ride.
