Reykjavik nightlife exists mostly on the weekends not sure about the holidays . Not sure how you can fit that into your schedule but FYI . Cool things to do in the city is walk around downtown and visit some of the museums National Museum of Iceland , Phallus Museum etc . The Blue Lagoon is not a full day thing more like 2 or 3 hours so you may want to couple that with something else . You also need to book that in advance as you can only enter by reservation and the tour companies take up a lot of slots very quickly . <| sep |> Happy thanksgiving everyone , I hate you all ! <| sep |> I ' ve seen a couple pedestrians steal a car I was about to get into , which is pretty cool . <| sep |> I know it does I only mentioned it because the latest KabyLake offerings sport only two cores .
