I disagree. The huge difference is that it will no longer be practical to use the DC for the iDine/RN restaurant miles program of your choice.
Right now, you can use DC MC for whichever program you prefer (since DC discontinued its own annoying discount program with the same partner), and it works pretty much at every restaurant, since (in my experience) they all take MC and all
give miles for MC. However, if you carry an Amex or Discover for dining, you have to hassle through checking the website for each restaurant before you dine, because the dining program doesn't autamitically give miles for Amex or Discover
even if the restaurant takes the card! So it's not enough to determine at the restaurant which cards it accepts.
So only a Visa or MC is essentially hassle-free with iDine/RN.
