I read in some other posts that this would be a good plan for a day long stop - Queenstown Heritage Centre, St Colman's Cathedral, Titanic Trail) and Fota (House, gardens and wildlife park). How far are these places from the port and what is the best way to get to these places? Should my parents do these in this particular order? They are 67 yo relatively active but poor English. They are arriving on Celebrity from 8 am to 9 pm. Thank you for advice.
