When I called Starwood Preferred Guest services, they were not able to enter my elite membership number. I guess not only will I be unable to get points for the stay, but I probably shouldn't expect a complimentary upgrade at check-in either.</font>
You should give your number at the time of chekin. You should get points for incidentals such as restaurants, drinks, movies...
You never know, they may give you something extra at that time.
