Great experience with Enterprise in Shannon. I researched before we traveled and heard it is a very good idea to purchase the additional insurance option since we're Americans and this driving experience is the total opposite from everything we've ever been taught about driving. So I did, for 142 Euro's for the week, with a 250 Euro deductible. Luckily we didn't need to use it, but it gave us peace of mind as I've heard the stories about loosing the passenger side mirror on small roads in Ireland, or scratches from driving too close to the shrubs.
Anyway, they were very detailed in explaining the contract to us. They even informed us of certain toll roads around the area and how to be prepared for that. We did not need the GPS option which they offered (I downloaded the Irish maps to my GPS before flying), but I would definitely recommend some sort of GPS whether you rent from them or do it yourself. Signage in Ireland can be a bit iffy.
So after going through all of the documentation and such, they give you the keys and send you off to drive in complete terror for the next day or so. The opposite side of car and road was quite frightening at first, but you'd be surprised how quickly you adapt to it. For me, it only took about a day. After that it started to actually feel natural.
The return process was a snap. We had no damage to our vehicle and they actually refunded us for turning the car in early in the day. I would definitely recommend them for rentals in Ireland, and I'll use them again when I go back. read more
