Crowd & price calls — sourced from our editors' on-the-ground reporting in Ireland plus published hotel ADR and visitor-arrival data. We tell you which months bottom out, not which ones marketing departments push.
Festivals & seasonal flags — verified against the official tourism authority and re-checked at every review. Where dates shift year-over-year (lunar calendars, religious festivals), we flag it explicitly.
Updates — this guide is reviewed by destination.com editors at least once a year and any time conditions on the ground change materially. Send corrections and we'll log them publicly.
