Affinity credit cards are all the rage these days. eBay's
So it only makes sense that you can spend your way into Vegas.
This morning, MGM Mirage
That's not a bad deal, and it should only get more appealing once MGM's merger with Mandalay Resort Group
The affinity credit card is yet another in a long line of tactics casino operators use to keep their customers' dollars to themselves and away from their competitors. Strip rival Caesars Entertainment
So which one to choose?
Well, if you have an eye toward the premium resorts on the Vegas Strip, MGM Mirage's card is the clear choice. Ditto if you frequently gamble at MGM Mirage's properties in either Detroit or Biloxi, Miss., both of which will participate in the program.
But if you're a low-to-mid-stakes gambler in a locals market (where patrons tend to visit several times a month) and Harrah's is your preferred hangout, then going for Harrah's card makes sense. Harrah's credit card rewards are directly linked to its Total Rewards players cards, so it all adds up -- plus it will also get you to a Harrah's property in Vegas. That should work out pretty well, so long as you weren't dead-set on staying at a high-end resort such as The Venetian next door, Mandalay Bay, or Bellagio.
