I wasn't able to get to D23 this year, and one of the items I wanted was the Tron themed monorail toy. I was hoping they had some left over to sell at the parks, and it turns out they did! Not sure how popular they were, but it's a neat little item for only $20.00 each (and you can use your AP discount to help that price a little!) Although they may be available other places in the park, the only place I saw them was at the World of Disney store. Before I found them I checked Star Traders, and Disneyana. In Ca Adventure I looked in Off the Page, and the store across the street from Disney Jr show (forgot the name) and none of them had them or knew about it. At WOD it's in the Tron toy section, on the middle shelf, so don't look for an obvious display. I got one of the Blue and Yellow ones. They either couldn't (or wouldn't) tell me how many they got, so to be safe if you want one head on down or contact DeliverEars sooner than later.
