Sounds like outdoors, dark, lots of people. I'd keep it simple and stick with the above from your list (you mistakenly didn't have cookies on your list?). I picked the 16-50 as it's your widest, but I'd also be tempted to just take your 35mm macro and the most compact tripod/support you have available. A little flashlight would also be handy.
Knowing the purpose of the outing, type of surroundings, expected light conditions, how far from 'home base' you'll be straying, and what you'd likely want to photograph would go a good distance to help with the planning
