Carnival Cruise Lines has announced longer cruises from Baltimore starting next year. The Carnival Pride will sail on a series of 10- to 14-day cruises to the Caribbean round trip and one way between Baltimore and San Juan, Puerto Rico, beginning in October 2015. Previously, Carnival’s cruises from Baltimore lasted seven days. Pride will also make five-day and six-day Bermuda cruises in 2015-16. On a six-day East Coast U.S. and Bahamas cruise from Baltimore in November 2015, Carnival will make its first scheduled stop in Charleston, South Carolina. This fall, Carnival Pride will undergo a multimillion-dollar makeover that will add dining, bar and entertainment options.
