1. cheapest good place to rent cars from Dublin Airport?
2. Reasonable driving time from Dublin Airport to Tralee?
3. 3 best hotels in or near Tralee?
(1) That'll depend on the size of car and dates, but you can compare rates from four different companies here.
(2) I'd estimate 4 hours or so. (Longer if you'll be arriving in Dublin during rush hour, as the M50 and M7 can get quite congested during peak times)
(3) See our Tralee Hotels page.
