I am traveling to Oahu and I was hoping to get some advice. I will be shooting mostly candid shots of my family and also attempting some landscape shots (North shore, pearl harbor, etc). As I am traveling with my family I will have limited time to scout my shots and I need to travel light.

I have a flipside 400AW and the following gear:
5d Mark iii
16-35mm L
24-70mm L
70-200mm ii L
35mm 1.4L
85mm 1.8
100mm L
2x extender
430EX
manfrotto tripod

Any suggestions as to what part of my kit is a must? I figure I can get 4-5 lenses in my bag.

thanks in advance.
