At the end of a week trip to Italy, my daughter (23) is arriving at KEF at 2:20 am on Sunday, July 8. She is planning on being picked up at the airport by the AirBnb (which is 5 minutes from the airport) and will sleep then through late morning. Check out time is 11 am. Her flight leaves that same evening at 9 pm. The Blue Lagoon is already sold out during the times that would be convenient. She would like to see some of the natural beauty of the area but has found that many of the tours start early in the morning or are based in Reykjavik. She would prefer not to rent a car unless necessary. Would appreciate any suggestions. Thank you!
