I love the purple too! I thought it was weird at first, since the marathon tech shirts and bibs are red, but I quickly got over it.
The expo was not crowded at all, but I went on Saturday of that weekend, so by the time I went the only other people there were non-Goofy marathon runners and people running the relay. No special D&B bags, so that wasn't an issue. I hope they have some this year, but I am wondering if they are only doing that for the women-centered races (Tink, Princess). I'll be at the expo on Thursday this year, so we'll see if it's more crowded!
Yep! The Christmas decorations were a nice treat. I'm hoping for them this year too, but I'm not sure since the marathon will be almost a week later than it was last year.

Fingers crossed!
