I've found the Amex rate can go one way or other. Sometimes more; sometimes less (and a zillion folk can access it given who their service provider is). The code posted above is probably accurate; haven't tried it.

If someone is actually trying a Hilton code, DONT put in the N. The system does that auto for you - just use the #.

I started a thread sev mths ago on sharing codes & got nada, zippo, no score response. Found it ironic given there's a 7-page thread on Marriott re: codes. Oh well.

Good luck all. Cheers. Sharon
