1) If it was an IC then you get no points for incidentals whatsoever. If it was another hotel in the group then yes you should get points.
2) This promo is stay 2 STAYS, not 2 nights and get 1 free! This will negate all base points however I'm still getting bonus points etc and on a recent IC stay received my Platinum bonus and RA bonus so walked away with 3k.
My advice is to play the Anywhere game...that should net you 3k - 4k and then you could always buy the other 2k required which would count towards status which would cost you $20 or something minimal like that.
..oh, and as far as I know even when you have completed your 10 stays you still do not get any points for the remainder of the promotion period!
