I have an Ambassador is is one of the top SPG Ambassadors for the past 5 years. While she is amazing in wanting to help like a travel agent, she knows virtually nothing about Marriott and how to navigate the system. I, basically, have to tell her how the system works and who to contact. I'm pretty sure that I would be better off navigating Marriott on my own but she really wants to help. I've learned that the thing she does best is contact hotels for future stays.
