i know I am quite a bit late, but as I have a few suggestions.

1. Minimum standards for premium rooms so properties (Hilton Sydney I am looking at you) can't get away with only having a very small percentage of their rooms listed as standard rooms.

2. A reasonable relationship between price of premium rooms and the points required. It makes no sense for an executive room to be 30% more than a standard room but cost well over double the points. This would mitigate the problem with my first point if that is not addressed.

3. This last point is likely hyper specific to people like me with smallish children. I often get two connecting rooms because my kids still nap and go to bed early. This means I never get a suite upgrade (unlike some on this board, as a diamond I have when I travel by myself). This is quite reasonable; however, it would be nice, subject to availability, if I could trade those two rooms for one suite at check in. For my family as long as there is a living area and sleeping area separated by a door and room for a roll away, it is better for us. (If point two was fixed, I would just use my points for a suite to begin with)
