They are big; they do not run narrow.

Still not true. We booked the first hotel night on our own.

You get a Helly Hansen waterproof pack and a beanie as well. The pack does not have a drink holder; it’s a dry bag with backpack straps. https://www.seabourn.com/en/us/packing-list/arctic-antarctica It looks like this: https://www.ebay.com/itm/285652804551

No, not true. We booked our own air travel and Seabourn provided us transportation to the hotel.

They provide wooden trekking poles. I suggest bringing a pair of your own collapsing poles. I found them useful.

Your cruise line should be providing binoculars which are fine, if you do not want to purchase these.

There is no need to bring boots or buy your own. The Bogs boots provided are perfectly comfortable. If you are on the Pursuit, boots are provided for free.

No, this is wrong. I work for a major airline and we can easily add or correct your Known Traveler Number on your reservation at the counter or a kiosk or you can do it yourself on the app.

No. Not on the cruise I took, but it did not visit Stanley/Falklands.

Yes.

No need to book kayaking twice. If your trip is cancelled, they will try and accommodate you. i was recently on the Pursuit and there was no need to prebook dining. There are also no shore expeditions to book. This is an expedition cruise.

Seabourn Antarctica ships do not carry 300+ passengers. The Pursuit and Venture hold 264 passengers. You will not do any camping in Antarctica, but the other activities you mentioned are available.

We booked the first hotel night in our own.

They do this for some passengers, but not all. Perhaps related to your Seabourn status? One couple did not get this benefit and they were very annoyed. We were staying an extra day in Buenos Aires, so didn’t do this.

We arrived one day before the official arrival day and paid for one night at the hotel and Seabourn paid for the next night (we were able to stay in the same room). My husband contacted Seabourn in advance. There was a Seabourn rep at EZE we checked in with and they sent us in a private car to the hotel at no cost. There were others on our cruise who did the same thing.
