Ireland rewards lingering. Many commenters advised fewer one-night hops and more hub-and-spoke stays (2–3 nights) so you can explore, rest, enjoy pubs and spontaneous detours without feeling rushed.
Expect slower driving on narrow roads
Irish country roads are often narrow, single-lane, and winding. Allow more time than maps suggest, drive cautiously, and factor in delays from agricultural vehicles and tourist coaches.
Rent a small car with full insurance
Choose a small car for tight roads and parking, get full insurance (recommended by multiple travellers) and consider paying a bit extra for reduced excess — it saved people lots of hassle after scrapes.
Plan daylight-friendly days and rest breaks
Especially outside summer, daylight is limited. Schedule long drives and scenic routes during daylight, include rest/contingency days for recovery or bad weather, and avoid too many back-to-back heavy hiking/driving days.
Base yourself strategically (or be flexible)
Either use 2–3 bases to explore regions or stay where you end the day rather than returning to a fixed base; both approaches were recommended. Consider Kenmare/Glengarriff over Killarney for quieter access to Kerry sights.
Pack/stock simple lunches and use deli counters
Bring packed lunches to sit and enjoy views (many wished they had). Local deli counters at Spar/Londis/petrol forecourts offer inexpensive hot and cold options — handy for day trips.
Prioritise key hikes/peninsulas and island trips
Don’t try to see everything. Highly recommended highlights include Dingle (Slea Head, Conor Pass), Ring of Kerry or Beara (not both in one day), Connemara, Slieve League, and Aran Islands (choose smaller islands for fewer crowds). Get local guidance for harder hikes like Carrauntoohil.
