Sounds daft I know, but ours has a four-inch gap all around the bottom. We used it for the first time last summer and assumed we'd put it up wrong. This afternoon we put it up in the garden to check it over and it seems there is no way to avoid a gap. Is this normal? After all the sleeping pods are enclosed with their own groundsheets so maybe it's just something we're meant to put up with? It's a bit draughty though and I'm not sure we're supposed to have starlings wandering in and out at will first thing in the morning, even if that was the highlight of dd's holiday! this is our tent .
