My apologies to moderators if this has already been answered - I could not find it anywhere in the stickies...

I was just told by a night manager of a Hilton in East Brunswick, New Jersey, that ALL reservations made through American Express (or Expedia, or Egencia, or... basically any third party) do not earn ANY HH points or stays that count towards status.

Is that true? It does not make much sense to me, but I am a Hilton newbie (will make Diamond for the first time this year). He also seemed to indicate that this policy may be property-dependent (which does not make much sense to me either).

Thank you in advance for your help!
