Can anyone help us, please? Next Monday on Feb 20 we are arriving in Dublin, have a rental car for 6 days and are basing ourselves in Bunratty. We just ran across something most confusing. "Drivers of all vehicles using the section of M50 between junction 6 and junction 7 are liable to pay a toll." They say there is no cash facility to pay the toll.....how does an American visitor pay?? There is more confusing information about being able to pay by quoting a vehicle registration number, by cash zone at pay zones nationwide etc etc.....Can anyone help us understand this?? many thanks!
