Low-cost rental tips
- Compare pickup spots: Check airport rates vs nearby towns. Local agencies can be cheaper, but factor in transport from NOC and limited Sunday hours.
- Book to the season: For Jun–Aug, lock in 6–8 weeks ahead. For May or Sep, 3–4 weeks is fine. Oct–Apr often sees good last-minute deals.
- Go small and be flexible: Smaller cars cost less and fit Ireland’s narrow roads. Being open to manual helps at NOC, where automatics are limited in summer.
- Check weekly pricing: A 7-day booking can be cheaper than 5–6 days. Run both options and compare totals.
- Plan fuel: There’s no station at the airport. Refill in Charlestown on the N17 about 15 km from NOC to avoid refuelling charges.
- Weigh one-way vs round-trip: If ending in Dublin, compare both. One-way drop fees from Knock typically start around €50+.
