With a good quality tent, stakes are not essential to withstanding weather. The rainfly and floor should overlap and fasten together at each pole end. The components form one integrated stand-alone structure. Stakes are needed only for accessory features like vents and vestibules, and to prevent the tent from blowing away when it is unoccupied. One good way to ensure this feature is to buy a four season tent, which is designed to be usable in the winter when the ground is frozen and snow covered.
