I don't know who all AMEX points work with, but you would get a much better deal if you could convert them into Airmiles that exchange with HHONORS. You only get 1300 Hilton points per 1000 MR points, but if you go into airmiles say Continental and then to HHonors points you get 2 for 1 on the Airmiles conversion.
