Going to be in the UK for two weeks starting in the midle of March. Which is the best way to get around the country, rent a car or take the train? I will be traveling alone and would like to keep costs down. Rental cars are only about $18.00 a day but I hear gas is expensive. Is there an unlimited travel ticket that can be purchased for the train like on the continent? (i.e eurail pass). Any help will be greatly appreciated. Thanks.
