I plan to take the Airlink bus to my hotel in Dublin and figure (correctly?) that they'll be easy to find at the arrivals area of the airport. My question is about the return trip - are there well posted signs/bus stops for these buses in the city proper? The website indicates that the bus stops at Wood Quay (close to my hotel) but it's not clear that there are actual specific stops or if you just flag down the bus. Yes, a weird question (I'm a detail person!), but I figured someone here will know. Thanks!
