I am going to go out on a limb here, and say that this would be one of the most fun ways to camp outside.
It gets you off the wet ground (though that puts cold air under you) and you can tether it anyway you like to maximize (or minimize) your swing-ability. This tent is made in England and will take about $600 out of the trail-mix fund.
It is rated to hold 150kg of camper (that’s about 330 pounds for those of us on this side of the pond) and is almost 5′ square around the bottom. So some might have to curl around a little to fit. Though for the camping kiddies… it’d be great.
