Perhaps you didn't talk to someone who knows what they are doing? I've been there before with Marriott...

(On an aside, if you are only making titanium for the 40k cert, I'd suggest stop at 50 nights and get the Marriott credit cards that give free certs on anniversary days. Think mine gives 35k certs. Worth the annual fee imo.)
