A private tour here is not a fixed route sold by the seat. You give a rough shape — the places that matter, the pace you want, whether you would rather see two things properly or five things briefly — and the day is built around that. The car is yours for the day, so a stop that turns out to be worth an extra hour simply gets an extra hour, and waiting at every stop is included rather than charged as extra time.
Longer trips run the same way across several days, with hotels and start times agreed as part of the itinerary. Runs to the west, the south, and across the border are priced as full days rather than by distance. Wicklow and Glendalough suit a first full day out of Dublin; the Boyne Valley for Newgrange and the sites around it; Kilkenny for a city day; the Cliffs of Moher and the west when you have a long day or an overnight to give it. These are the routes clients ask for most — an itinerary you have written yourself works just as well. Entry tickets, tours, guides, and meals stay yours to book; the car, the driver, and the fixed price agreed in advance are what's included.
