One more negative with Hilton - they do really take your points if you have no activity for a year. That scenario may seem hard to imagine at the moment - but if you change programs or travel to locations where you can't/don't use Hilton, when you hit the 12 month mark your points are GONE. (no warning) Happened to me twice - I know that I am responsible for the loss but traveling so much doesn't leave me a lot of time to bother with bothersome details - therefore Marriott stays my favorite. As stated in another thread, I have never heard of them dumping someones points for inactivity.
