I contacted the general manger of the downtown Sheraton Hotel, and asked him what the future plans were for the Century Center. Here is his response:

Patrick,
We are going to do about a 200K face lift on the interior. The work will begin within the next thirty days and will include paint and carpet. Our plans are to convert a portion of the space to additional meeting and exhibition space. The balance of the space, mainly street frontage will be actively marketing for lease space.
Have a good week,
