Ditto to that. Practically all vehicles in the British Isles come with manual transmissions. The wife and I went to Ireland last year, and we wisely rented an automatic when we left Dublin. (You can get around Dublin quite nicely on the city buses.) You'll pay more, but it was worth it. Driving on the left side of the very narrow Irish roads was tricky enough without having to work a manual transmission. Strangely enough I enjoyed doing the roundabouts which I thought were going to give me a lot of trouble. Great trip though, Ireland was fantastic. I highly recommend driving yourself rather than going on a tour bus. You'll see a lot more.
The drive out of Dublin down through Bray and beyond is beautiful, along the cliffs overlooking the Irish Sea, some parts of Dublin itself are, too. I stayed at either Jurys Christchurch or a small place out in Ballsbridge.
That’ll because at our roundabouts, people do tend to give way. This isn’t Paris, you know!
