We have flannel sheets year-round that seem to keep us comfortable in cold or hot weather. If we are camping a lot in the summer, there's a better chance the sheets will get changed more often than a couple times' use even with the A/C going in the summer. The dang are difficult to change because of our configuration with the bathroom and wardrobe up on the "out" side of the bed and the back wall on the far side. I do the job, but I don't have to like it! 😛

I wasn't sure how to reply to the poll. We all use sleeping bags, but line them with either regular or flannel sheets, depending on our preference. We do wash the sheets when we think they need it, if we've been sweaty or sick, used insect repellant in the evening, if we've camped in sand, etc., but don't have a certain number of nights quota.

In our PUP the boys use the beds not only for sleeping but for lounging, which for them requires food (which inevitably creates crumbs) requires washing bedding asap to keep the ants and such away - we don't have a problem with this because if extra laundry is the only bad part about having them spend a weekend camping with us, that's more than fine.
