I have 52 HH points. Not 52000, but 52. However, I have a 40k redemption booked.

If I cancel the redemption, I will have 40052 HH points. This is probably a 'top 20,000' number worth 8k PC points. However, I will not be able to rebook my HH night for 40k as it now needs 50k.

Can PC actually check the HH totals? I know they will ask the winner for full verification, but not all 20,000 I'm sure ....

EDIT - found the T&C's:

What if I've been asked to submit additional verification?
In order to be eligible to receive the 20% point value or the 2 million point Luckiest Loser prize, we must verify your balance and need a current copy of your online Hilton HHonors account activity showing your available HHonors Rewards Points.

How do I submit this additional verification?
You may submit the statement either by fax to (770-642-8893) or by first class mail to (P.O. Box 157 Roswell Ga 30077) or upload to (www.priorityclub.com/lostsomething). If submitting by fax or by mail, HHonors activity statement must be accompanied by a separate piece of paper on which you have printed your full name and your Priority Club Rewards member number. If submitting online, include the above information in the submission form and upload your Hilton HHonors activity statement as a JPEG or PDF file 2 MB or smaller. Faxed and online submissions must be received by 11:59:59 PM (ET) on 2/28/10; mailed submissions must be received by 3/5/10. Limit one submission per PCR Member.

So, on this basis, I may submit the 40000 number. If I am in the top 20k and am asked for extra proof, I will decide at that point whether to cancel my HH reservation (to get my points balance back up) or not. I am, of course, then stuck with 40k HH points which are increasingly tricky to use.
