According to "Frequent Flyer Bonuses" thread on MP posted today, the winner of the HHonors membership voting for the Q4 bonus offer is the "DoubleUp" offer, where after the second stay at a participating property, you'll receive double the points for that stay. Details from the thread with a link to register on the Hilton website: http://milepoint.com/forums/threads/daily-bonus-offers-highlight.8643/page-30#post-2471844 I was able to register easily, and noticed that on the "NON-Participating Properties" list, in some instances a few of the properties that had opted out for the Q3 bonus offer were not shown in the new, current list of non-participants. Most London, UK, and some Canadian properties no longer show on the NON list that were on the former one, which is a slight improvement. I'm not 100 % clear on whether AFTER your second stay at a participating property, you'd ALSO then receive the bonus points for the first stay which triggered the offer for your next stay, but I'd guess the answer is a NO, but just a guess as I didn't see a direct answer to that supposition. Also, what if your FIRST stay is at a NON-participant property (but still a paid stay generating regular points and other regular bonuses and miles), then your SECOND stay is at a participating property, would that still be acceptable to get you the DOUBLEUP Bonus on the second stay? Probably not I think, but also not specified directly in the FAQ's for this new bonus offer.
