12 nights for 12,000 points...77.5K total for 20 nights over goal. Doubt I'll make 32 (more) nights.
Also, from the T&C:
4.9. Program Participant only receives credit for Qualified Hotel Night Stays occurring after he/she becomes a Program Participant. Qualified Hotel Night Stays occurring during the Offer Period but prior to registration in the Program will not count toward completion of an Offer.
Looks like we'll have to cancel and rebook.
