Hmm, the FX converter I use (Oanda.com) indicates that 1000 ISK is around $8.45 today($1 = 130 ISK), so the FlyBus would be around $18.50. For those of you planning to take the FlyBus, please be aware that it will take you to a Central Terminal where you have to change to a smaller bus that will take you to your hotel with potential stops at other hotels along the way (and yes, you'll have to transfer your bags yourself--at least we did the last time we were there). We chose to do a private van because since there are six of us it is only slightly more and a lot less hassle. If you're interested the website is www.shuttleservice.is. Be sure you look at the fares from KEF rather than from the domestic airport. They also have a public shuttle that will take you directly to your hotel, but there may be other people at other hotels on that shuttle so you may still have several stops, but you won't have to change buses.
