Dream with me: Alaska cruise, money is no object

[Mad Hungarian]

Have mercy on him! It took me months to process my own 4000 Alaska cruise photos. I think my policy of "digital is cheap, so snap lots of shots" needs some revising. Digital may be cheap, but my time isn't...

I might be doing another Alaska cruise myself next year, and i'll probably be taking up something like this:
* A pair of Canon 6D bodies (still need to buy that second 6D).
* 24x105, or 24-70 f/4 IS (if i actually buy the 24-70 f/4).
* 16-35 f/4 IS (my most recent purchase).
* 70-300L
* 400mm f/5.6 (or maybe 100-400 MkII if it comes out and is good and i can afford it).
* 100mm L macro.
* Maybe a 135 f/2 or 200mm f/2.8 for clandestine shots of any show i'm unfortunate enough to find myself in.

* A flash of some sort. Last year i took up my 580ex, but i only used it to snap shots of my cabin. Those cabins are tiny enough that a 90ex would've been fine...
* A light tripod (Gitzo 1542T with small ballhead) for panos and waterfalls.
* My Guragear Bataflea 32L for storing all the stuff in. And my little Lowepro PhotoSport 200AW pack for carrying a subset of stuff on excursions. They both worked pretty well last year.

* The idea of renting a BIG LENS is tempting too. Though i'd be scared or losing or water-damaging it. Renting's not cheap though. I was looking at LensRental prices, and it's approaching $1000 for a 500 or 200-400 with insurance. And i'm still out $1000 if it gets stolen, or $12,000 if it gets wet! I wonder how i'd carry the thing too. It's too big for my Lowepro, and my Bataflae is really too big & pretentious to be carrying around much. Need to buy another backpack? And i suppose i'd need a heavier tripod & head too.
