We have driven all over Iceland with no problems. We are planning on renting from Avis. There are two docks in Reykjavik. One is further out from town and the other is right downtown. Explorer was at the downtown one when we embarked there before, while when we embarked on Regent, mariner was at the one a bit further away. At any rate, they will pick up and deliver if it is too far to walk to the office.
