If you are doing a cliffs of Moher trip stay away. Schedule is way too tight, times at sights are limited and you have a 50-50 chance of getting a driver barking orders at people, driving like a maniac and threatening to leave you behind if you are less than 5 minutes early (yes early, not late).
Definitely a no-go.
