So Amazon packages are generally delivered by carrier. The post office will often reject a package that’s mailed using snail mail directly to the property if the address doesn’t match. They won’t get residency at your place because they sent a package.
On a side note - I’ve had things delivered to me at a hotel before. Sometimes people just need to be able to get things.
Just make it clear to your guest that you won’t take responsibility for deliveries - ship at your own risk!
