If I book a travel package through Costco (air, car, hotel) and choose a package that has a Marriott hotel, will I be eligible for Marriott points and room night credits?
Looking into this for you, Surgie! I'll message you back once I learn more.
No, you won't get credits toward elite status or points but you will get other platinum benefits such as CL access.
sorry I was typing exactly the same response while you were.
Yeah, it's a bummer isn't it?
A bummer that you don't get points or elite status, that is! Not a bummer that we both gave the same answer
Generally you do not get points or credits for points packaged through a third party. There have been posts on here that you may get some benefits such as lounge access if you are gold or platinum. Check the terms and conditions in the sign on page.
Thanks for the helpful answers everyone. You're all correct - booking made through anyone other than the hotel or Marriott International itself are not eligible for points or credit.
