Now that Boston has a new convention centre, new hotels are opening to serve it. The latest is the Westin Boston Waterfront which officially opens today. The 793-room hotel is less than 3 miles from Logan Airport (BOS) and is connected to the Boston Convention & Exhibition Center in South Boston. Guestrooms are equipped with wireless high-speed Internet access (for a fee), and in-room coffeemakers with Starbucks coffee.
