Staying in the car as we explored Maui was an AMAZING experience. Jay gave great recommendations about where to stay, where to snorkel, places to visit, and more. He was very responsive and fun. Overall, having the flexibility to go wherever we wanted on the island allowed us to see 10x more than we would've otherwise.
The Ford Explorer we got had everything we needed to camp out on our vacation - a bed for 2, table, chairs, snorkel gear, camp stove, kitchen supplies, and more. Note that the car is older, not all fancy like a rental car, and some of the things didn't work super well (car usb charger, flashlights, etc.) because all the gear has been used plenty before. This is something to note on your trip, but none of it was really a big deal. For the price and flexibility it gave us, Jay's place was the perfect way to spend the week and 100% worth it!!!! As long as you are prepared to rough it a little and have appropriate expectations, Jay's campers will be awesome and unique 😀.
