I wrote this and posted it on my blog when I was facing some expiring Hilton Points - 7 Ways to Prevent Your Hilton HHonors Points From Expiring

Since you need at least 1 eligible point earning activity every 12 months I don't think that will work. But you can cancel and rebook yourself directly through Hilton.

Here's a summary of the post
1) Use a free site like awardwallet to stay organized
2) Use your Hilton credit card
3) Use HonorsDining to earn points when you eat out
4) Shop with a Hilton partner business to earn points
5) Buy points - $12.50 for 1,000 Hilton Points
6) Stay at a Hilton
7) Donate points to charity
