Hi , we are in Sweden atm but planning to leave Gothenburg on 18 April 2023 by Stenna ferry to Frederikshavn catching the 18.20 ferry. However our train does not get into Gothenburg until 17.40 that day. Am wondering if that is enough time to get to the ferry? (Not sure how early you have to get to the ferry before it leaves) Also any ideas how to get to the ferry port? Any trains?
