I've read the thread and I'm almost there in figuring out how it works. I want to stay on points in a Towers room for six nights in the second half of November. I'm SPG Gold. Is it correct that I can book a standard (deluxe) room now for 60k points and then contact the SPG Gold desk to upgrade to a Towers room? It should be about 2,500 points per night extra, but the upgrade won't be confirmed until something like five days before the arrival date? Do all the rooms in the Towers receive access to the Towers lounge and free breakfast?
