The Sheraton Delhi -- distinct from the Maurya (Sheraton) -- seems to maybe have forgotten to load standard rooms available for online booking with Starwood points. I've stayed there when it was a Marriott and when it was unaffiliated, but haven't yet been back since it was flagged as a Sheraton several weeks back. I'll be there in a couple of days and would be interested to see what, if anything, has improved.
