We went on a road trip and did some camping recently. If you haven't got all the gear, one place we stayed we got a "yurt," which cost about $14 a night - a little round cabin with electricity, basic mattresses, and a little heater. It was the perfect thing for us, and I would totally do it again. One of the things I hate about tenting is how you can't stand up and dirt always gets tracked inside. The yurt eliminates both of those issues. Also, you can bring regular bedding if you don't have sleeping bags, and they have locks so you can stash your stuff inside during the day. I think a lot of national parks are starting to try these out now.
