Myself and three friends are heading to Ireland in January for a week. We have booked a 'Castle Tour', which just means we have pre-arranged places to stay in 'castles' each night. We have a car, so will be driving between them and able to do our own thing during the days. We have been reading Ireland for Dummies, and it has us spooked about parking. As it is, we aren't going to spend any time in Dublin, the biggest city we will probably go into will be Cork. We would like to see many of the points of interest that are open during January, but the book made it sound like the only way to stop in and see things in a town is if you are taking the bus, otherwise parking is a problem. Is this going to be an issue in the cities or towns or am I overblowing this whole thing? Thanks!
