Hilton’s 3rd quarter promotion runs between July 1 and September 30, 2012 where you can earn either double or triple HHonors points:
- Double points: Monday, Tuesday, Wednesday, Thursday nights
- Triple points: Friday, Saturday, and Sunday nights
You must first register prior to check out to be awarded the bonus points. Keep in mind though, that this is only for participating hotel and unfortunately there are many that have opted out (MANY in the US and London).
