I have usually given my name/players card. Over a 10 year period, I have worn my name out at MGM, Harrahs, Station, Ameristar, etc. A few years ago, these places weren't well connected- I was personna non-grata at Mirage and NYNY in Las Vegas but scoring monster comps at Gold Stike. Eventually, I have wore most of them out.
I have always gone by "Billy" even though my Drivers License says "William". All my bank accounts are "Billy" so this would be a very simple change. Would that be enough for me to get some fresh lives and start getting rooms and comps?
