My specific questions: (1) Would bus or train be the best way to get from Dublin to Cork? (2) Should we skip Glendalough in order to see Bru na Boinne? For anybody willing to help with anguished choices, here is the background: Four of us are leaving in two weeks for a two-week visit to Ireland, our first. We are flying into Dublin and out of Shannon. We'd intended to rent a car as we left Dublin and head south through Glendalough to Kilkenny, then making our way west through Kinsale to Dingle and up towards Connemara, where we have the use of a house for four or five days. We also intended to see a few things in a leisurely way rather than try to see everything in a rushed way. But the guide books erode such intentions by listing so many must-sees! So now we are thinking of staying an extra day in Dublin in order to see Bru na Boinne. To do this we are thinking of maybe skipping Glendalough. This raises the possibility, after we've done Dublin, of getting ourselves efficiently to Cork and renting our car there for the rest of the trip. Any comments or advice would be gratefully accepted.
