How many of you take a flash on your visit? If so, do you really end up using it that much? Have a long trip coming up (EBPC cruise and the World) and it is just me and the wife so I don't have to worry about taking family shots, etc. Trying to talk myself out of taking yet another piece of gear that I may use twice considering the way my shot list looks like right now. It's bad enough I have to remind myself to NOT pack the macro - gotta draw the line somewhere?
