Unfortunately we can't get very close using Streetview so will have to settle with a long view taken from the public road outside. You can vaguely see that it looks the same although Marriot seems to have undergone a re-branding at some point and changed the style of their logo.
So, why was the Marriot featured in Yellowthread Street when other nearby hotels such as the Conrad and Shangri-La were still under construction. It appears that the Marriot was built in the very first construction phase of Pacific Place and so was ready by 1988 - a year or so before the series was made. The neighbouring hotels were part of a later phase completed in 1990.
Additional Edit: I forgot to add the snaps from inside the Marriot lobby when I posted this, so here they are.
The distinctive metal pillars in the background can also be seen on this shot taken by a traveller and uploaded to the Tripadvisor website (link: http://media-cdn.tripadvisor.com/media/photo-s/02/ed/0d/ec/jw-marriott-hotel-hong.jpg)
