Hold the phones -- there may be a way!
I just came across something about SPG on Harrahs website, so I ran a Google search and came up with this:
(sorry - I'm too tech illiterate to figure out how to just post the link)
Harrah's teams with Starwood, Westin offers 5:1 Starpoints for player points
Harrah's has teamed up with Starwood to offer extra incentive to earn Total Reward points.
Total Rewards is Harrah's player's club program, and while gaming at a Harrah's property anywhere in the country, you'll receive points that you can exchange for merchandise or freeplay.
Now, you'll also be able to earn Total Rewards points when you purchase nights at a participating Starwood Preferred Guest hotel property. This includes competitor Westin in Las Vegas, down the street from Bally's on Flamingo.
Through the end of the year, every $1 spent on an SPG hotel will gain you 2 extra bonus reward credits. And you'll still get your regular 2 Starpoints for each $1 as well.
Note also that currently at Westin Las Vegas, if you visit the player's club to link your player's card to your Starwoods account, you'll receive 500 Starpoints for every 100 player points (1 point = $1 coin-in).
