As first-time visitors to Oahu, we found it more adventurous and economical to combine our housing and car rental into one = camper van! Our trip was short, but the ability to camp each night allowed us to enjoy many different parts (with the least amount of time in busy Honolulu). The hosts were exceptionally responsive and gave lots of useful advice on places to stay all over the island as well as tips on local eats near the pick-up location. The bedding was very clean, solar-powered fridge and lights worked great, van ran reliably, fit a ton of luggage. Lots of awesome beach goods included like chairs, blankets, and snorkling gear. Only thing I did not enjoy was the sink, which had a bad smell coming from the drain and the water pump was very weak. If you decide to do drop off at the airport, give yourself extra time to walk from the parking location to catch an international flight.
