More than three weeks is considered extended use. The tent should still hold up fine, but it is extended use and would not be covered under the warranty. The wall stakes are considerably lighter duty than those 10 stakes to protect the tent in the event of a crazy windstorm. You do not want that enclosure to tear where it attaches to the tent. It's best to let the wind (in a worst-case scenario) pull up the awning as opposed to tear the awning from the tent itself. There are some crazy windstorms. It is the same with the vestibule. It intentionally has thinks that generally allow it to be pulled out of the ground in the event of extreme wind. If you do upgrade the stakes keep that in mind.
