Current MR Gold will become the new MR Plat, hence you will get Breakfast at lounge or at the restaurant depending the property arrangement.
Assuming
Elice is a full Marriott Gold with 50 EQN in Marriott in 2017 or who has qualified in 2018.
If you were MR Gold thanks to a few SPG stays and a status match over to Marriott, I believe that ends on Aug 1.
