Hi everyone, Firstly, this is a super insightful thread - thank you!
My wife is the primary cardholder of Amex Biz Plat. I dont have an authorized user. However, I do have an Amex biz gold card. My wife doesn't have Marriott status, but I'm a Platinum elite.
When booking a FHR hotel to trigger the $300 statement credit, if I put HER name as the primary contact and MY marriott number, will that trigger the $300 credit and $100 hotel credit? And since the marriott is under my membership, I can use my NUA for a suite upgrade request, right?

I hope that makes sense - just want to clarify before booking. Thanks!
