Since there unfortunately is no Iceland-specific forum, I figure this is the next best place to ask:
For those of you who have traveled to Reykjavik, do you recommend pre-booking a shuttle from Keflavik airport to Reykjavik? Or is there a bus that leaves the airport regularly enough to be able to catch one once we clear customs/passport control? Also, if we do not pre-book said shuttle, would you recommend taking out cash from an airport ATM to pay for it, or is it convenient enough to pay with a credit card?
Thanks!
