I'm new here, but my sister got a code today, and I didn't. We are booked to go at the same time, different reservations and diff. hotels. I called WDW and asked if I had a pin, and they said no, but to give my sister my resv. # and get her to call back and apply the pin to my resv. She did, and it worked. They said a pin can be used for up to 3 rooms, and didn't say anything about it having to be a relative, or living in the same household. She saved on her reservation, and I saved on my reservation. Hope this helps someone.
