I think I have been getting multiple room nights credit this year - having a 9 year old, we often get two rooms with a connecting door and I had a few stays where a co-workers room was in my name. In any case, the web site claims I had way more nights this year than I think it should have. Of course the details are hard to figure out from the web site since it doesn't just show nights per credit - but somehow I ended up with more nights than I should have. I did not see this miraculous night increase last year - it's definitely a new development - possibly since I finally got my LTT status.
