1. Add platinum authorized user
2. Authorized user can make their own amex online account and book their room in their name
3. The $200 amex travel credit was credited
4. Close the authorized user card. The $175 fee is refundable within 30 days of adding the AU.
5. enjoy your stay. The platinum card does not need to be open at the time of stay since it's prepaid.
Since this conversation was moved to another thread, I scrolled up and found this post.
So this seems like the safest strategy. I ask my parents to add me as a Plat user to their account, add the card to my login, book FHR, get the $200 credit, and close the card for a refund of the annual fee.
