I noticed a few weeks ago that the upgrade language has been changed again. Suites are no longer specifically excluded. Language as to upgrades only to next room category level is gone. This follows extensive complaining here, on Facebook, and Marriott Rewards Insiders. New language:"For Platinum Elite members the best way is up! So every time you check in, we'll do our best to upgrade you to a premium room - at no additional charge – for your entire stay. Upgrades may include rooms with desirable views, rooms on high floors, corner rooms, rooms with special amenities, rooms on Executive Floors, or suites, subject to availability identified by each hotel. See terms and conditions for details." Of course, there are still plenty of weasel words there.
