Pay my airfare and I will do it for you .

Outside.... lots of light generally speaking....

I would think an extension tube to cover the macro stuff and leave your macro lens and the 50mm home if you are looking to save weight and bulk. The 70-200 makes are pretty good flexible macro (heavy etc but IQ is there - is it the IS version?)

I am not a fish-eye kind of guy, might look at renting the 10-22 if you need something wider.

I am thinking your are doing pretty good. Are planning shots of the beach bonfires, etc.? Then the 1.4 is a good idea.
