When our tour group departs from the Dublin airport, we plan to take a train across Ireland and have 3 nights in the West before we depart from Shannon airport. We're wondering if we will have time to go to Dingle and get back close to the airport to spend the last night before we leave? Is it even worth going to Dingle in such a short amount of time? The other option we can think of is to take the train from Dublin & spend the last 3 nights somewhere near Shannon such as Adare or Limerick. Much appreciate any feedback, ideas, suggestions, advice!
