- No Blackout dates. Marriott is touting this as an important feature- but this does not guarantee that standard rooms will be available. However, for people wanting to stay at a particular hotel who have a lot of points this could be good.
- Redeem for 4 nights and get the 5th night free.
- For Platinum members, increase of points bonus from 30% to 50%. This is good if you happen to be a Platinum member (you have to stay 75 nights in a year to achieve Platinum)
