I was targeted for this and the additional 10k for Extend Your Stay promo, doing a mattress run for this at a $67 per night. Should rack in ~55k CC points, plus 5% back through mrrebates and credit card spend.
Also keep in mind the MEGAPTS offer for another 10k per night at select hotels. I am not near any but if you are could be very lucrative.
