Baggage Limits on Expedition cruises

We were on the Silver Explorer to Antarctica, Falkland Is. & So. Georgia in Jan. 2016. There were no formal nights, not even sport jackets required -- a very casual environment. I would hope on the Cloud that it would be the same. There are baggage weight limits for these expedition cruises.

I think you'll find there will be no baggage weight limits on the Cloud when she sails to the poles as the ship will only embark 200 passengers whereas she was designed for 50% more.

Are there baggage limits on the Charter flight to Ushuaia?

Was told that we fly to Santiago Chile, spend a night at the designated hotel, then all of us board a charter flight.

I just have visions of some small aircraft to fly us there.
