My first attempt to cross the border between Marriott Rewards and SPG and I was cheated out of nights and points. I recently booked a hotel through a conference website. I had the option to go with a few Marriott's or a Starwood hotel. I made the wrong choice. Everyone that stayed at the Marriott hotels received nights and points. I, however, was told that Starwood does not give nights and points when booking a conference block. Has anyone else had this problem? Two different set of rules for Rewards and SPG. I spoke with the front desk, called the customer service line and sent two emails. They all say the same thing: Starwood won't honor points/nights for conference blocks, even though all the Marriott hotels did.
