BILOXI — Pictures of the proposed 500-room hotel at the Mississippi Coast Convention Center have been revealed but it’s still undetermined what company will operate the $100 million hotel.

Tom Lander, general manager of Mortenson Development, the company hired by the Coliseum Commission to design and build a convention hotel in Biloxi, said Thursday the hotel is based on a Sheraton design, but officials are not committed to Sheraton.

The Sun Herald reports (http://bit.ly/qs85SP ) plans call for a maximum 14-story hotel off U.S. Highway 90, oriented north-south to give guest room views of the sunrise and sunset over the water.

The hotel includes a full-service restaurant, a 10,000-square-foot ballroom, 5,000-square-foot junior ballroom and 5,000 square feet of breakout rooms.
