Please be aware that if you are booking a reservation for any MGM Resort in Las Vegas that MGM will charge you an additional "Resort Fee" of $25 per day (for the use of the workout facilities, parking, phone and internet use) . I will be in Vegas on business and the only thing I will be using is the internet (will be busy with meetings and not parking on site), so $25 a day for internet is way too much pay. Yes you save 10% off your reservation, but your savings is nullified with the "resort fee". It would add an additional $100 for a 4 night stay. I called to talk about the additional fee and was told they would not waive it. My suggestion is to call around, try booking through the travel center and find a resort that does not add additional fees. So this 10% savings offers to the membership is a big rip-off.
