Searched the forum but couldn't find anything quickly. I have a 5 night rewards stay booked for Sydney Harbor Marriott in May for my honeymoon. Should I order the e-cert now? or just wait until Marriott automatically orders me one 7 days prior? I guess the risk is the hotel category level or redemption levels could change? or am I locked in at 120,000 points with my reservation no matter when I order the redemption cert? Not that I plan to need the points anytime between now and then but would rather have the option.
