The wife and I are going to Ireland this fall, and booked a train/bus tour, going all over the country. Several people have said we should have booked a car and driven ourselves. No thanks, I drive too much for work, and I want to be able to just relax and look around as we travel, not be concentrating on which side of the road I need to be on, and any other vehicles or sheep in the road. 99% of the time, when traveling internationally, I would rather book a tour than plan it myself.
