I started off in a tent when I got there to save some money.
I then got a caravan at kona waters. Was $260 a week and you can share.
There is more comradery at the backpackers with all the crew, but after getting to work at 4am and leaving past 6pm most days the last thing you want to do is talk shop and dick wave with the Slingair boys.
I'd recommend getting on the waiting list for a van at kona now!
