Will someone offer their thoughts about the Expo for first-time runners? I know we'll have to pick up packets in person but how long should we expect to be at the Expo? Is there transportation offered to the Expo or do we take our own car? Trying to figure out how much time it will take out of the day and any times better than others to go.
One other thing - merchandise at the Expo - is a lot of it generic runDisney stuff you would see the same at each race, or is most of it specific to that particular race?
The time at the Expo will be completely up to you. Packet & shirt pickup can take 10-20 mins, depending on lines. Outside of that you can leave immediately, or spend hours checking out the booths, and attending presentations. If you have no need for sparkly skirts, and brought all the gels/goos/sneakers you need, the Expo can be really quick. But if you have a habit of buying all sorts of new things to run in, and find some of the speakers interesting, you can spend a chunk of time there. If you are staying at a WDW host resort (IE one that has transportation to the race start) there will also be transportation to the Expo. I believe that the normal WWoS bus runs as well, but the runDisney expo buses are usually a more direct route.
The merch is a mix of both. And even the generic runDisney stuff isn't always the same from event to event. Maybe 25% runDisney stuff, to 75% event specific. But of that 75%, keep in mind that they often have the same thing for each event in the weekend. So in January they will have maybe 10 things, that are done in Dopey, Goofy, Mickey and Donald. Same exact stuff, just different colors with a different logo on it. Expect a short sleeve tech shirt, long sleeve tech shirt, track jacket of some sort, hoody, pint glass, wine glass, sweatyband/bondiband, sticker, magnet, running hat, pin. Throw in a "I Did It" shirt and a "In Training for..." shirt, and you pretty much have the standard runDisney merchandise.
