1. 1 Marriot Pt becomes 1 Airline Mile Becomes 2 Hilton Pts. Using a 175k Aloha 6 night Aloha award u get a 6 night hawaii award for 87.5k Marriott Pts, a savings of 120k pts of a normal Marriott 6 night Hawaii award.

2. Everyone eventually needs to use a Hilton or Starwood when Marriotts are unavailable or perhaps where a friend's wedding is. In this case, you can use those spare pts along with converted pts to get a nice award.
