We had a true aft balcony Deck 8 on the Oosterdam SA - Antarctic cruise (BA to Santiago) this past Feb . I had worries about rough seas making it unusable, envisioning giant waves crashing onto the balcony ! Despite some rough weather and seas, we used it everyday and enjoyed the easy access to the lido deck , pools, hot tubs, and Seaview bar , as well as the views .
We only used seasickness meds one day , and once we got use to things , never again. It was no worse in our cabin than the rest of the ship . I think that was the day poster 0106 referenced .
We would get an aft cabin again on the same voyage , which we do hope to do again someday. It was a great cruise and exceeded expectations in everyway 😊
