Has anyone been to Iceland? It's pretty much at the top of our list for our vacation this May. Iceland Air flies directly from Orlando to Iceland which is awesome- no layovers! We may also fly from Iceland to London for a couple of days, and then fly from London to Orlando (all through Iceland Air). We'd rent a car (of course) and stay in a few places around the country. There's one main highway which connects in a circle around Iceland. There are itineraries listed in guide books and online, but I'd like to hear any details from people on here who have been. The other places that we're considering are Bolivia, Peru, and Alaska. The high elevation in Peru and Bolivia is my big concern- I have asthma and I don't want to have issues breathing the whole time. I spoke with my doctor about it last year and she said it shouldn't be a problem, but it still worries me. So... experiences with visiting any of these?
