I'm in your situation too. I'm not making a big fuss though, I just go to the office every day and always take the same desk. I leave the desk clean at the end of the day, but I just put the things in the drawer under the desk, where people are kind enough to leave my stuff alone. If one day I find someone at my desk, I'll just go to a different desk (it happened only once).
