Awesome option for staying in Oahu for those who are "Glamping" inclined. Check-in was smooth, and the van had everything we needed, including two pairs of snorkels for shoreline adventuring. We even swam with the sea turtles at Laniakea beach!
There are also a couple of beach chairs and and a bodyboard provided for more beach fun.
The sink/shower was such a great help for keeping things clean, and leaving the beach at the beach.
I definitely recommend staying your nights at Malaekahana Beach Campground. That way you can avoid the stress of possibly having law officials knocking at your door for sleeping in your car on public land. It's a beautiful spot, and they are also one of the only, if not the only, campsites that allows car sleeping without having a tent up. Even their "tent sites" allow you to just sleep in the van, sans tent.
Overall really great experience.
