I was always recognized as a Platinum member, get upgraded to suit and get my welcome amenity on arrival..also late check out till 7:00 PM...no problem.... do u stay mostly in sheraton's or westin's?... I found that westin staff better than sheraton staff...
the other question is when you check in does it show that you are platinum in there system?...if yes and you dont get upgraded, thats strange!...which hotels did you stay at?..are they in the US?...more detalis please..
Good Luck
