If it's not too much trouble I'd recommend sending feedback about your experiences (MI rewards associates for guest feedback and uses negative feedback to identify areas to improve)

You can send feedback via marriott.com or send Bill and letter via USPS to:
J Willard Marriott Jr.
Chairman/CEO
Marriott International, Inc.
10400 Fernwood Road
Bethesda, MD 20817-1102

Marriott can certainly track the associate you spoke with regarding the mega bonus, and all GM's love receiving notes from HQ's about great guests experiences
