Reserve an automatic early
22 visitors said this
Manuals dominate rental fleets and the automatics run out.

Download offline maps and carry a paper road atlas
12 visitors said this

Don't rely on credit-card rental cover without a letter that names Ireland

Photograph or film every panel of the rental
6 visitors said this
