We will arrive in Shannon near the end of June, staying for about four days but realistically having about 3 days to tour. We are thinking about a cruise out of Doolin (?) of the Cliffs of Moher and the Arran Islands--I think I'm spelling those names wrong! That cruise says it is 6 hrs long. The other two days might be going to Limerick on a bus and Galway on a bus. Can we get a bus from the Shannon airport that will take us into Galway and Limerick or should we look for a day tour? Are we missing some other wonderful spot the we could fit in? We think we will stay at Bunratty Villa or around there so we can do the castle the day we arrive. Thanks for any advice!
