I would take everything. Dont forget extra batteries, chargers, filters, sensor and lens cleaning kit, etc. A water housing might even be a good idea for unique photos. Also think well about camera support options (tripods/heads) and gear storage/carrying.
Regarding choosing between the 100-400L and the 70-300L...The 70-300L is weather sealed but the 100-400L has more reach. But since you have the 7D id take the 70-300L on the 7D and use the 5D3 with the other lenses. Most likely the 17-40L.

Doesn't the trip cost around $30,000?
Depends on what you do and who you go with. The one I went on was 16,000 a person triple occupancy. You can go for as low as 5,000 to 6,000 to just go to the peninsula. The one we went on was relatively pricey because it was an icebreaker and had helicopters to chopper you to locations.
It unfortunately is not offered anymore as Quark Expeditions no longer has a contract with the ice breaker ship, Kapitan Khlebnikov
went with lindblad/national geo last december...everything you imagined and more...two well known Nat Geo photographers were on board,both not only lectured and shared images but went out of their way to be accessible to look at your images and advise on technical and artistic issues, you could approach them anytime...bring everything within reason...I am the kind of guy who gets self-conscious when I take more expensive and sophisticated equipment than everyone around me...no worries in antarctica....everyone was armed with two camera bodies and multiple L lenses, never seen so much equipment...I used the 70-300 L and the 24-105 L mostly...I would agree with extending to South Georgia as well if you can...I just rejoined here and dont have any idea how to upload photos and my only online galleries were with Mobile Me on mac.com which just got cancelled so I can't show you any of my shots....email if you want and I can send you some...have a great trip, I would do it again in a heartbeat, aloha...peter
allan: there are no land-based predators there, so most of the animals will let you approach close...not like africa where you need all the reach you can get...incidentally I am in process of setting up a shutterfly gallery and will send you link....only have a few antarctica shots up so far but you might be interested in the antarctica (very brief) video......

I HIGHLY recommend doing the triangle (rather than just down and back) since in many respects, the other two places are more impressive than Antarctica. Picture below is South Georgia with several hundred thousand penguins in a gorgeous scenic setting.
Thanks for sharing all that. Will love to go to Antarctica one day.
