re: Just booked tix to Iceland for April

My wife and I are going with another couple the first week of March. We were initially sold on the cheap flight to see the Northern Lights but after looking more into all Iceland has to offer, I'm getting more excited about going to check out the lagoons, glaciers, etc. As someone else mentioned, the TripAdvisor folks recommend you not rent a car in winter. So I started looking into some overnight tours to the South coast and they look good, but I hate the idea of being on someone else's schedule for everything. Plus, you're always around groups of people. Wondering if we should just rent a car in Reykjavik for a day or two so we can drive to the Golden Circle on our own and then maybe look into a tour as well. We only have four days so it's a pretty quick trip. Enjoyed reading this thread for ideas. Anyone that's been over there in winter, I'd like to hear how the experience was... Seems like it would be totally different compared to going in August.
