We are planning a trip in June 2014 to Ireland and Scotland. We would like to take the ferry from Belfast. I know flying is faster, relatively cheap, but #1 I hate to fly--getting back/forth to US will be all I can handle #2 DH is concerned about luggage restrictions/fees on various airlines, even though we plan to back as light as possible. Our problem is finding a car rental that we can use in Republic & Northern Ireland, and take to Scotland, returning to Dublin. I just see where earlier posts say that both ferry lines have been moved to Cairnryan. Are there car rental offices at terminal? If not, what would be the closest place? Thank you in advance.
