I was out there some years ago on a business trip, and from what I can remember, there isn't an awful amount of room to move around and the stalls are all crammed together, draped in lights and goodies.
What I will be after is trying to capture the atmosphere in context ( if you know what I mean).
I have the 24-105L, but not had the MKlll that long to see how it is in tight spaces, maybe I should take it into town and see how it does in the streets.
Is it just me, or is there a lack of choice in wide 2.8 lenses for FF?
