There is an alternative to tents that not many know about- geodesic domes. I've built several and now prefer them over regular tents when staying at a campground more than 2 days.(These are not for backpacking!). Don't panic, it's easier to build them than you think. I found the following site last year,it has instructions for building them out of electrical conduit.Conduit is a lot stronger than you think by the way. It takes some effort to construct one but it's well worth it.
