We travel with our best family friends a few times per year and we caught Iceland towards the beginning of whats now an all-out tourist blitz on the country. It's an amazingly beautiful place (especially during the summer) with close to 24 hours of daylight (it never really gets pitch black dark). It has hundreds, if not thousands, of stunning waterfalls, glaciers, volcanos, lava fields, martian-like landscapes one minute and glacier lagoons the next. By far our favorite trip ever. If you love the outdoors/nature, highly suggest you go. They're opening a new route from Miami for only $200 round trip starting in April, already planning a return trip.
Fun fact, Miami-Dade county has almost 8X more people than the entire country of Iceland.
