Want to do something more adventurous, fun and easy going? You can camp almost anywhere, cook for yourself and save yourself the cost of a rental car and accommodations. The vans come with all you could need including heat and cooking supplies. Here are the best companies I found.
Compared rentals in North America car rentals are pretty cheap. Only about 20-100 euros a day($22-120). I highly recommend getting gravel road insurance. Get a fuel efficient vehicle because gas is pretty pricy($1,70-2.08 USD/Litre).

Iceland is not somewhere you visit for the food. Great view definetly, life changing experiences absolutely. Food no. It's expensive and not very full of taste. You have to keep in mind that it's an island and anything they don't grow or raise themselves needs to be imported. So things like fruit, veggies, beef and alcohol are very expensive. But a few veggies, sheep, goat and fish you can get for a much better price. You can save yourself a lot of money by grocery shopping and cooking yourself if you decide to stay in an airbnb or in a van. Cheap meals are $25-30 per person in a budget restaurant. Below are some budgets but are aaruming that you'll eat out and buy snacks from the grocery story.
I will share a two links below for flight from Las Vegas to Reykjavik or to Hofn. You'll need to check, if you decide to rent a car to make sure you rent it from the right city. The capital will have more options and likely will be cheaper. I highly recommend since you're already flying all the way over that you stay got at least 5 days. The flight is the most expensive part.
When you're looking at flights or any bookings look at them using incognito mode. Otherwise the prices will be more expensive.
