Two waterfront hotels on St. Pete Beach have sold for a combined $100 million, according commercial real estate firm Holliday Fenoglio Fowler. Together, the Grand Plaza Hotel and the Beachcomber Beach Resort have 258 rooms and span more than 9 acres. The hotels were sold by Excel Hospitality Inc. and purchased by Miami investment company Gencom. Benchmark, a global hospitality company, will manage the properties. The Grand Plaza Resort at 5250 Gulf Boulevard opened in 1975 but was renovated in the last five years. The Beachcomber Beach Resort and Hotel is less than a quarter-mile away at 6200 Gulf Boulevard. “The Tampa Bay region continues to be a magnet for hospitality investment, drawn by its vibrant, diverse economy and tremendous leisure and recreation amenities,” Daniel Peek, the head of Holliday Fenoglio Fowler's hotel group, said in a statement.
