I am here for a conference only, but being an experienced conference goer and presenter, this is just my impression of the set up.
The fact that the presenter is late is not the fault of the hotel, BUT, the room is very cold, and although Starbucks coffee, tea and the condiments have been set up in the room, there is a screen and 2 white boards, the carpet and drapes are shabby, with some of the drapes hanging off the hooks and none of the tables set with pads, pencils, or pens from Marriott which is usually customary no matter who is sponsoring the event.
