We are planning to take the train from Belfast to Dublin, then catching the Swift ferry to Holyhead, Wales. I'm concerned about the transfer time between Connolly and the ferry port. We will be traveling on Saturday, May 20th at the end of our Best of Ireland tour. There is a train from Belfast at 10:35 that is scheduled to arrive at 12:40. The Swift ferry departs at 13:50, and the latest one can check in is 30 minutes prior to departure, so 13:20. Given the short connection, we're planning to take a taxi. Is 40 minutes enough time to transfer between the station and the Irish Ferries terminal and get checked in?
