Pay the extra money and rent a car with an automatic transmission. I drove nearly 800 miles trying to get used to shifting with my left hand after driving standards over here all my life. I got used to the left side thing, after a few near misses, but I never got use to the shifting left handed. We sort of just "winged it" and just town hopped across the whole Eastern half of the Island. I didn't see all I wanted to because we went to the UK too. This was in 1997, so things are probably a bit different now. The one thing that surprised me was how good the food was nearly everywhere....even little pubs, etc. It isn't cheap by any means, but it was good.
