First time going to Okinawa this summer and wanted to rent a car. From my research it looks like all of the rental car companies are offsite from the airport and seem to be pretty far ie not walking distance. Any recommendations for place that are walking distance from the airport or a short shuttle ride? Also would it be difficult to find parking throughout the island for a 8 passenger van or it it better to have 2 smaller vehicles.
