I had a trip planned to Alaska next month and when I rent to book my rental I had to cancel my flight. The flights from Buffalo to Ancourage were cheaper than I've ever seen, I thought there had to be a catch and there was. It was $3500 for a rental car for 10 days up there, just insanity. They are renting Uhauls up there and using them instead, but with gas so high it would be similar pricing.
Instead I booked a trip to Montana, Idaho, and Wyoming for $1000 for 10 days. Air bnb prices were pretty cheap up there for next month. 2k total for 10 days isn't too bad to explore yellowstone, tetons, and glacier national park. Plan to hike about 100 miles in 10 days up there. Let me know if you have any questions about Iceland, I went there for 2 weeks a couple years ago. Still my favorite trip of all time.
