And if more and more people do it, there will be less and less chance of getting it consistently, even with the work. When booking went online, things tightened up because it was easier to stalk reservations - future changes may make it even more difficult. There are only so many standard studios, and a lot of demand. Plus, there is the risk that you end up moving rooms - perhaps even more than once, if the holes don't fill in your reservation.
Don't count on them. Try for them, sure. Perhaps even work for them if you want. But understand that you might end up with nothing, or a split stay. And if you are operating with a limited number of points to start with, you could find yourself without the room you started with, and without the room you were going for.
