I'm new to the entire rewards system as I just got the new SPG Luxury card from AMEX. I know that my status will automatically be upgraded to Gold Elite, but I'm not sure when they'll bump me up. I'm looking to book a few nights for my next trip. Would you recommend me to wait until Marriott upgrade my status or should I book now with no status as I'm not sure what the room rate is going to be. Any advise is appreciated.
