I am considering renting a car at Dublin airport. I have read varying experiences with rental agencies, the good, the bad and the ugly. I have done my homework on end, confirmed with my credit card company they cover "loss of use" among extras. But I fear based on the reviews of others this may not be enough? The rental price is alluring for sure, almost too good to be true, so I have to wonder, what's the catch? I've considered Conn's Ireland Car Rental - but still want to be sure I am making the best decision. Has anyone else dealt with Donnelly's, Hertz (although this is a definite NO with a $5,000 hold on my credit card), Europcar, and their wallets have lived to tell the tale?
