Agencies there. I’d look up some info like if you had to rent a Turo right now for you to use with in the next 2hrs in Hawaii would there be options. That will give an idea of how easy it would be to rent another car if your Turo reservation bails. We rented through Turo in Florida 30A area. Had a scare because our Turo reservation contact didn’t respond to texts for about 15 min after we got there and there were no other Turo rentals for that time in that area.
