My first marathon and loved it. Expo is small but still very good. You have to buy the Mizuno slipper clogs though! They are really comfy to wear around the house.
Course is dead flat. Towards the end there is a very slight incline out of an underpass. It is nothing, but after running a completely flat course (and you see it coming a mile off) it looks like a mountain.
Bag drop off very efficient. Start is inside the stadium and there are plenty of toilets in the pens.
The finish is great, running around the running track in the stadium.
I'll be back one day, definitely.
