rmccamy: I can see how that happened. I'd rather have your 5 for 10 also rather than my 5 for 5! It's interesting, because I stayed almost exclusively at Mariotts well into 1998 and in 1999 switched to Hilton mostly. You'd think they'd want to encourage my return more than they have. There probably is an algorithm somewhere that formulates the individual offer, but I prefer your random number generator theory. It seems to make the most sense if there is any to be made.
