Issued in late March, the RFP said the company was seeking an agency to "manage the... components of an overall [PR] program, including media relations, social media, crisis communications, and special events."
The RFP also said that NCL expects its new agency to supply a separate team to launch a series of new cruise ships set to sail in 2010.
The winning agency will be tasked with creating buzz for the new ships, which will be based on a nontraditional format.
NCL representatives did not return calls for comment in time for publication.
Written responses were due April 18, while a second round is scheduled for May with a maximum of five candidates progressing to this stage.
Edelman, which was NCL's previous AOR, said it declined to re-pitch, according to the firm's EVP Kate Karet.
According to the RFP, the contract would last one year with an option to renew for an additional year.
