With Friday’s Bermuda sailing of the Norwegian Dawn, the Massachusetts Port Authority (Massport) launches the 2013 cruise season at Cruiseport Boston’s Black Falcon Terminal in South Boston. New this year, Massport is offering travelers free wireless Internet access at the cruise terminal to meet traveler’s expectations to be mobile enabled. More than 80% of vacation travelers bring at least one device, such as a smartphone, e-reader or laptop with them on vacation and 65 percent of travelers have used free wifi in an accommodations lobby or common area, according to a national electronics retailer. Cruiseport Boston’s free wifi service is supported by advertising and sponsorship programs.
