in that case, call and talk to a TM for help at UO reservations
in fact, if you ask the TM how can i get the room for the best discount?, they will guide you and tell you the difference.
that is what i did when i read about the promo SMSM.
i had the other discount applied as i booked jan 3rd for my fall trip.
i switched to the 'stay more save more' a month ago as that price beat what i was paying.
i am there for 8 days so i did get the max discount on the room.
