I've gotten a few emails from them re: upgrading an account to Gold Elite. Costs $450/yr, has 100k bonus for a $5k spend and has says "Plus, you’ll receive complimentary Marriott Bonvoy™ Gold Elite status, including 25% more points, Enhanced Room Upgrades and more."
I'm still a relative newbie and don't understand what Gold Elite would do. Any idea if this is worthwhile?
