The Bad: The tent makes you a target for the homeless. Do not leave this car anywhere that you see homeless walking around in the bushes, riding bikes slow, etc. They will full on walk up to the window and look in... EVEN WHILE YOU ARE IN THE CAR. The homeless are also at almost every beach on the west, south, and east costs. North coast is about the only homeless free area. Be sure to keep the car in eye sight at all times.
Check in is a pain. Cost us a $60 Uber ride to get to the vehicle, but I can understand why they leave it where they do given the Oahu homeless epidemic.
The good: Extremely cozy! We had a few nights of absolutely insane rain, and we were completely dry and warm inside. The provided amenities in the car are everything you could need for a good time at the beach, hiking, camping, etc.
Make sure to book your campgrounds well in advance. They are not kidding that everything is sold out pretty much all the time.
I would 100% rent this again!
