Dublin to Dingle on the Friday will ltake around five hours. Dingle to Kenmare on Saturday will be two hours plus just under an hour more to Sneem. Dingle back to Dublin on Sunday another five hours. With only eight or nine hours daylight you will be on the road most of the daylight hours.
You wont see much of Dingle. Why not stay in Kenmare if that is where you want to be?
30 minutes from Kenmore to Sneem is not realistic. 45 minutes would be pushing it. I usually use the AA Routefinder to get distances and times. Their times are a little more realistic than Googles estimates.
I'd say 45 minutes or so.... http://www.theaa.ie/routes/ is what I use too and my advise would be to add about 20% to the driving time...the KMs are very accurate though...Edited: 26 December 2015, 05:45
