Exploring Maui while camping is an awesome experience. The car is well equipped and Christine has a lot of insider tips she shares with you. She's very helpful with any questions.
Unfortunately, there's a deposit requested on the day before check-in which I didn't know. Maybe I didn't read properly but you have to send 500 dollar via Airbnb. If you return the car you'll get it back. Just be aware that Airbnb keeps a certain amount of the money and call it "conversion fee of your bank" if you pay in a different currency. It's not about 12 dollar more or less. But it feels like a hidden cost you don't know about before and somehow left me a bad taste in the mouth.
