If I've got the story straight, the fire started in the next-door multi-story Dynasty building complex in an apartment tower, spread to that complexes' hotel tower, then crossed over to singe part of the top floor(s) of the Sheraton. Sounds like it wasn't the Sheraton that was fully engulfed, but that they got some blowback and damage. That close to a major fire, there's bound to be serious smoke affect even if the flames didn't get bad. Of course, there could be more accurate details still to come. Funny that a lot of the English language stories on this incident (that I've seen) mention "evacuating the Sheraton staff as a precaution..." with no mention about evacuating any Sheraton guests.
