I received an email today from MLife reminding me to renew my MLife tier match status with my Hyatt elite status. Last year, MLife (MGM hotels rewards program) and the Hyatt Gold Passport program teamed up to offer crossover rewards in both programs when you stay at an MGM hotel. If you have elite status with Hyatt, you can have your status matched in the MLife program, which I wrote about in the past. I recently stayed in Vegas and reviewed my stay at the Monte Carlo and Mandalay Bay, and it was very useful having my MLife gold status and skipping the long check in lines over the weekend. As long as you have a Chase Hyatt Credit Card (which already has one of the best sign up bonuses of any credit card in the market) you already qualify for MLife Gold Status. You can find a list of the Tier Program Benefits here.
Also, make sure to log into MLife for discounted rates at the following hotels: Bellagio, Aria, Vdara, MGM Grand, The Signature at MGM Grand, Mandalay Bay, Delano Las Vegas, The Mirage, Monte Carlo, New York-New York, Luxor, and Excalibur. MLife members can save hundreds of dollars off of rooms at these hotels!
