Just to put the distance from Lahinch to Dingle in context, the physical ditance is about 75 miles give or take. True given decent roads this is easily achievable in 2 hours. However you also have to consider the ferry crossing, the time waiting for the ferry, loading the ferry, unloading the ferry, that bloody caravan doing 25 miles an hour on a narrow winding road etc etc. There is plenty to see and do closer to Lahinch, do that justice and plan the next trip to the Dingle peninsula would be my considered advice. hope you have a great time. Post a thread to say how you went on
