Right, @Gyrocket I've double checked with the land lady.. There's one spare bed available, bedding provided. If anyone is desperate there is apparently a couch. (I'd suggest bedding isn't supplied for the couch)
In any case I'll lock you in for it. Not 100% sure on cost but somewhere round $75 each.
Apologies @richiesmith that puts us at capacity.
In case you missed it though, the Awakino pub do (or did last year) offer a shuttle service to and from the Seaview Holiday Park and .. well anywhere locally if you arrange it, so that's an option if you find something a little further out.
Seaview seemed to have plenty of little cabins but don't supply bedding.
