Private tours are in high demand due to limited number of vehicles, especially during peak travel seasons and public holidays such as St. Patrick’s Day, Easter, and Christmas. For these busy periods, guests often book six months to a year in advance. Outside of peak times, booking a few months ahead is usually sufficient — but we always recommend reaching out as soon as you have a date in mind. It’s worth enquiring even last-minute, as occasional cancellations can free up availability.
