We woke up when our alarm went off the next morning, so there must not have been Northern Lights overnight (not like that was a surprise, given how hard it was snowing when we went to bed). We packed up our bags, stuffed ourselves again at the buffet breakfast, and checked out. As much as I didn't want to leave, it was time to head home.
We got to the airport with plenty of time to spare, turned in the rental car, and went to the terminal. We had to wait a while to check in because we were so early. but the ticket counter eventually opened up, we checked in, and cleared security fairly quickly. We had plenty of time to hit up the duty free whiskey section and grab lunch before clearing customs and heading out to the plane.
Overall, this was a fantastic trip, and probably the best trip I've ever had to Iceland. It was absolutely beautiful in the winter, and while Reykjavik is a cool city, it was a lot of fun to stay in different places for a change and go at our own pace with the rental car. I'm not sure yet when I'll get back to Iceland, but I know I will someday!
