A 3 season free standing tent is most appropriate because you can’t find nice soft grass everywhere to stake out a tarp and you need it to be waterproof. Doug64 is right. How does a tarp work on hard ground ya can’t get a stake into? I tried a Tarptent squall? 2 for a few nights and hated it. Waste of money if you aren’t in the ideal campsite. TNF Tadpole 2 works well for me.
