Donna (kohalagal) when are you in Waterford?
Name of your ship? depending on the draught of your ship you may well dock in Dunmore East or Waterford city right on the Quay or down river in Belleport- about three miles away or even in Great Island. One would have to know that information.
If you dock in the city, you are beside the centre and within walking distance of Reginalds Tower where Strongbow and Aoife were married a "little" while ago.! It's a must see. The Crystal factory is a short drive outside the city about three miles or so. (Taxi or city bus)
You will get a lot of info' on your ship about shopping etc and they will likely have a list of cafes, restaurants, pubs etc.(You can always seek same in advance from www.southireland.com ,an independent tourism body)
If you dock outside, let's say in Dummore East, you can stay in the village -very beautiful with plenty of food available and all within walking distance.Also your ship will have tour coaches and taxis available to bring you on a short tour of Waterford including the Crystal factory and the surrounding villages. (You book those on ship some days before arrival in Waterford)
Come back if you want more info'
