Well, T-minus 12 days until cruise time, and based on the wife's wishes and budgetary factors, I think we're set. For me, 5DsR, 600/4, 1.4x TC III; 1Dx, 70-300L; 5D3, 24-70/2.8II; 14/2.8II in a pouch. For her, 1Dx, 100-400II, 1.4x TC at times (she'll have to learn to choose whether aperture and AF points trump reach; personally, I suspect the TC won't get a lick of use, but that's not for me to decide); 5D4, 24-105/4IS v1; 11-24/4 in a Shootsac and probably the 100/2.8 IS L Macro as well. I'd certainly prefer the 100-400 over the 70-300L, but I just can't bring myself to rent another 100-400 and leave an otherwise-fine 70-300 behind.

We do have a custom private photography excursion booked for Skagway/Dyea, and for that we'll take the remainder of our prime collection in case something strikes our fancy, which includes the 35/1.4II, 50/1.2, 85/1.2II, and 135/2. I want the 24/1.4II as well, but can't justify it based on its look alone (and certainly don't anticipate needing it for the aperture).
