Portland’s planning board has approved the construction of two new hotels in the city. The hotels approved Tuesday will add more than 230 rooms and two restaurants to the Old Port area over the next few years. A 131-room Courtyard by Marriott with 14 penthouse apartments was approved near the Portland Fish Pier. The $17.5 million project is expected to start next month and open in June 2014. The board also approved a 110-room hotel and restaurant to be located in the former Portland Press Herald/Maine Sunday Telegram building across from City Hall. The $8 million project is expected to get under way this summer and be finished by mid-2014.
