Walmart tents can be a great way for your family to go camping without breaking the bank. If you have a disability, you may want to consider a low profile tent. They are easy to maneuver and you can walk around in them. They provide plenty of floor space for your family and you. With a square foot of floor space, you can easily fit an inflatable mattress, a sleeping bag, or all your personal gear. If you intend to change into your tent, you'll need a place to sit. Generally, 25-30 square feet will do the trick.
