We loved our stay at the barrels. We were two families who booked both barrels, and the kids absolutely loved the novelty of sleeping in a barrel. Highlights were the flying fox, marshmallows on the fire, jumping net, and the chickens.
Unfortunately it rained the whole time we were there. Annika's place will be even better once they build the outside awning and there is more covered space. And take insect repellent!
