Hello! My husband, 3 year old daughter and myself will be flying into KEF airport on December 31st this year, staying for one night in the city center of Reykjavik, then going to the blue lagoon on the 1st of January early morning for a few hours before heading back to the KEF airport to catch our evening flight back home. My question is, do we take the bus from the airport to the hotel on the 31st? And then pay for a shuttle to take us from our hotel (the next morning) to the blue lagoon and then to the airport? Our flight gets into KEF on the 31st at 3:40pm. So I'm not sure if we will still have some daylight left at that point or if it will already be dark? If it will still be light out, would it be easier/quicker to just rent a car for $110 total and be on our own schedule (which would be helpful having a 3 year old in tow)? Or do we just pay for a bus to our hotel (not sure of the exact cost) in addition to the shuttle from our hotel-> blue lagoon -> KEF airport which was around $150 total. I feel like it may be cheaper to get the car rental. I'm just not sure of the driving conditions on the roads this time of year or if driving in the dark will be okay. Any advice/tips are appreciated. :) Thanks!
