I didn't read the fine print, but it says it's good on hotel, spa, dining and entertainment. Not available on retail. Here's the website with all the details: http://www.MGMResortsGiftCard.com I'm definitely going to pick up a few for my next trip. It will save me $20 on three nights of Mirage resort fees alone.
