Thanks Satori for that link. Great review. I travel to a lot of "out of the way" towns, so loyalty for Hilton means I'm not staying in the top notch hotels a lot of the time anyway. Even when I've gotten upgrades, I haven't noticed a big difference in the rooms anyway.

Have you had any experience redeeming your Hotels.com rewards? There is something in the T&C about only being able to use 1 reward night per booking. Can you get around this by using 2 reward nights at the same hotel as separate bookings for back-to-back days?

Also, they limit it to 10 free nights earned per year. I might end up going back to HH once I reach the limit if that's the case.
