We sailed to Antartica this year from Ushuaia, Argentina across the Drake Passage on a Viking Expedition ship and never lost internet capability. We were in very rough seas in the Drake but we could still connect. We could do wifi calling, emails, get on any website we needed to for work or otherwise for the entire time we were in Antartica, over a week. Viking uses Starlink on these ships and it works great! I agree, if Princess is going to make the claim they have the best Wifi at sea, its time to make a change. We have also sailed Princess two years ago to Alaska and the wifi was terrible.
