In August, we rented a car for a day from Reykjavik Rent a Car, telephone 354-569-3300, or info@reykjavikrentacar. Address Knarrarvogur, Space 2, 104 Reykjavik (right off 41). It was $134 for 24 hours. It would have been less if rented longer. We were four adults on a cruise ship and had made our own reservations to spend the afternoon and part of the evening at The Blue Lagoon. Didn't realize that The Blue Lagoon is 45 minutes drive from Reykjavik. It was going to cost us $250 for a cab and one coach transfer company wanted $110 per person. We didn't want to take a bus. The rental company sent a shuttle to pick us up around noon and we used the car the next morning to ride around Reykajavik, park and walk downtown. Then we returned it and the shuttle took us back to the ship. It was easy to drive there.
