Four of us adults will be arriving early morning into KEF airport and need to arrange transportation to Blue Lagoon/Silica Hotel, where we will stay one night. Next day, we will need transportation from Silica Hotel to our hotel near Hallgrimskirkja. Suggestions on best way to do so? Flybus both segments? I think there’s a Flybus transfer from airport to Reykjavik that includes a stop at the Blue Lagoon, but can it be split over two days? If there’s four of us, does a taxi make more sense? Any advice is much appreciated!
