Things I wish I knew:
Food is more expensive than I thought
We're talking about $20 per meal. If you're staying at a place where you can cook, you can buy groceries at Bonus.
I didn't need to pack so much thermalwear
I took the Ice in Iceland pretty literally and being the warm-blooded Texan that I am - I packed as many layers as possible. In reality, all I needed was a good wool coat. Granted, I visited in April - so there was no snow. But my baggage was filled with clothes I didn't even use.
Northern lights tours end April 15
And I arrived April 18. I thought that I could drive to secluded places and see the northern lights - no luck. It didn't get dark until 10:00 PM and it got light at 4:00 AM.
I didn't really neeeed a four wheel drive car
I drove around the Golden Circle, Vík, and to Jökulsárlón (Glacier Lagoon). I didn't go off road often so I felt a bit ridiculous with this 4 wheel drive SUV for one. Not to mention it needed diesel gas and cost about $80 to fill. I should note that it wasn't snowing, terribly windy or rainy.
The blue lagoon costs about $100 for a ticket (which you must buy in advance)
Was it worth it? I'm still on the fence about that. But I truly enjoyed the experience! I got the comfortable package which comes with a free drink and a clay mask. It felt like a luxurious spa and I certainly didn't regret it.
You have to pay for several things
Especially if you're staying at a hostel. You have to rent towels, locks, sometimes even sheets.
