The 184 standard 500-square-foot guest rooms are augmented with three sizes of suites - 1,040, 2,100 and 2,600 square feet. Opening of the 200-room, six-story hotel just northwest of Rohnert Park is set for Nov. Soon the $800 million Graton Resort & Casino, already a gaming and entertainment center, will feature a place to stay over by some guests who arrived on on expanded tour bus routes, to attend a conference or -perhaps one day- flew in from Mexico into nearby Santa Rosa.
