We fly in to Keflavik at 7am on a Sunday. We plan to soak in the Blue Lagoon after arrival, en route to Reykjavik. We will have to pick up our car rental from Blue Car Rental, then drive just under 30 mins to the Blue Lagoon. I'm curious how long it usually takes to get through customs at KEF upon arrival, so I can figure out the timing of our Blue Lagoon entry. Does anyone have any tips/experience with this?
Thank you!
