What downtown still doesn't have is enough hotel rooms. But that will change this next year with the opening of the Skirvin Hilton, Colcord Hotel, Bricktown Hampton Inn and Lower Bricktown Residence Inn. At least two more hotels are being discussed behind the scenes. By late 2007, downtown's room count will top 1,600.
