Hopefully, Carnival will consider keeping a 7 day cruise ship in Tampa long term. For now, I am sure many Tampa cruisers are excited to have some additional options. No information has been announced about cruises from Baltimore during the months the Carnival Pride is in Tampa. Carnival did note, in their press release, after sailing from Tampa the Carnival Pride will return to Baltimore.
