I don't travel often, but my company has an Emerald account with National. I cannot tell you how easy it is to be able to bypass the rental counter and just pick a vehicle that suits me on the Emerald Isle. The staff at the Toronto airport location was fantastic and when my colleague left his cell phone in the vehicle upon our return, they called me and we were able to recover it before our flight. Great service, great car and great price. What more can you ask for?
