I have purchased a Sceptre package for the Adare Manor Villas, and a car included for 6 nights, 7days. The package does not include the car insurance. Sceptre says I can purchase scdw with them and save money by purchasing in dollars. The quoted price is $178.00, which doesn't seem that great to me. Should I just wait and get it upon rental at Dan Dooley's at Dublin airport? I'd appreciate any imput.
