No matter which Coleman tent you buy, the 8, 6 or 4 person instant tents have some things in common. They are all designed to set up in under a minute, they have large windows allowing for great views and excellent circulation and they are high quality, so no worries about those darned zippers failing. In addition, these tents are extremely rain and weather proof, so no worries about getting rained, blowing away through the campground or being flattened by a collapsing tent.
These shelters should last a lifetime, so be sure to purchase a gift for a camper that allows ample room and comfort for the entire family. The Coleman 8 person is the largest available, and has a convenient divider for privacy that is easily removed. Even if the campers on your list aren't a large group, having the extra room to store clothing and other camping gear, even a portable toilet, will make the outing much more enjoyable. These tents are so large that one room can be used to play games in on a rainy day instead of everyone being smooshed in a small area, grumbling at one another.
Coleman's 6 and 4 person tents look very similar. They vary in floor space, available in 10x9 and 8x7 sizes. Most importantly, they differ in height. The instant tent 6 has a center height of six feet, the 4 person stands at five feet. The height is really an important factor. My husband and I are both very tall, and there is nothing worse than having to bend over to change clothes, etc.
My personal recommendation is that Coleman Instant Tent 8 person model is the best. Even a couple will enjoy having the extra room and space inside for their outdoor gear. Campers know that when tents proclaim the number of people they will hold, companies think in terms of a can of sardines. 6 people do not, in fact, fit comfortably in a six person shelter unless stacked side by side and on top of one another! For the avid camper, the best camping gift would be, in my opinion, the roomy eight person model.
Now just grab a bag of marshmallows and some roasting sticks and you're ready for the outdoors!
