I'm a solo traveler who don't want to drive. I know that, if I drive, I'll get to many cool places otherwise hard to reach by public transportation. But then I'll be looking at the road most of the time and I'll also be tired by the time I reach the sights.
I like to take 3-week trips of a single country, spending 2-4 nights in each stop. Taking short flights and joining local small group tours are options I'd consider.
So, is it a good idea for me to plan a travel in Ireland by public transportation? (And for that matter, Scotland? England?) So far, the Ireland trip reports I've seen in this forum are all for road trips.
