It depends... on lots of things you can't control, unfortunately. I don't care to linger at expos, so I try to get in and out quickly, and I've alwyas been able to do that in the past. Not so this year for Dopey. I drive and my plan was to go straight to the expo at about 1pm, grab a bite to eat, get my stuff, and get out. But traffic was backed up so far, it would have been at least 30 mins for me to even get into the parking lot. So I turned around and ate at a resort. Checked in with friends and they reported a loooong line just to get into the WWOS complex. I tried again about an hour later and was able to park easily, and even got into the complex, but then had a long line to get into the Field House to pick up my Dopey stuff. I didn't even bother with the expo in the J Center, as the line to get in wound all the way around the soccer fields.
I don't know why that happened - I've never seen it that bad at any other race. And I hope it doesn't happen again, but I'm mentally preparing for it, just in case.
