I'm going on a Caribbean cruise the week after next, and I'm trying to figure out what photography "essentials" I should bring with me, and what to leave at home. Here's what I'm thinking of bringing so far: Rebel XT body batteries charger 10-22 24-70 2.8L 70-200 2.8 IS 50mm 1.8 The "light" tripod, which is not quite as sturdy as the big one, but should do ok Laptop Leaving at home: Flash 8mm Peleng Fisheye 18-55 kit lens "big" tripod I've never been on a cruise before, so I don't know how cumbersome it might be to lug stuff around, or if it will intrude on my good time with my wife. I just don't want to leave something at home, look at something and think, "damn, wish I would have brought that lens." Any advice or testamonial is appreciated. I dunno if this is the right forum for this; move it if its appropriate.
