What shelter you use to camp in is just a matter of taste. It may also be a matter of health, as some people just cannot sleep on the ground, for example. On that note, many tent campers may want to stay away from campgrounds made for RVs or campgrounds that get heavy RV use. This isn't a matter of looking down on RVers, but tent campers may want an area to themselves. Many campgrounds are set up to put tent campers away from the others for this purpose.
Tents are the least expensive shelter, of course.
They can store in your closet, along with sleeping bags. If you want to hike 6 miles to a primitive campsite, you can do so with your tent. A variety of tents on the market may make purchasing one a tough choice. The one factor we suggest on a tent is having screen windows on more than one side, to allow breezes to blow through. This helps air out the tent, and in Florida, you'll likely want that breeze on most days.
