Dave Middleton and Jim Gibbons of Young Electric Sign Co., put the final touches on the new Provo Marriott Hotel sign. Sunstone Hotel Investors, based in San Clemente, Calif., bought the former Provo Park Hotel along with others nationwide to franchise out. Workers inside are finishing a $5 million renovation of guest rooms, dining areas and the front lobby. Allie's American Grill and JW's Steakhouse, which will open at the end of May, are new to the hotel. Seasons, a private club, will remain. The 333-room hotel was originally known as the Excelsior.
