My only thoughts are to spend enough time wherever you stop. I always wanted to stay longer in each place...I personally think Killarney National Park, Muckross House, the lakes, is amazing and I could have stayed there forever! We had beautiful sunny weather every day but one, so we were spoiled. Donegal is beautiful too, but I can't think of a place I really didn't like....I know they have had tons of rain there this summer and last summer, so I hope it all clears up for you before November.
Hi Scott! Welcome to the site, I am new here too. Have you been to Ireland? I just went for the first time in May. My grandfather's family came from Ireland, like everyone else's, during the famine, but I never thought much about it....until my grandmother took my daughter and I along with my mom and aunt. I fell in love with the country and the people! I can't wait to go back!
