I am pretty knowledgable when it comes to the cigar bars on board cruise ships. I will not take a cruise on a ship that is not cigar friendly. A big part of the enjoyment of the cruise is to be able to smoke a cigar indoors in a comfortable environment when the weather is inclement.
I have been in the Carona Cigar Lounge on the Norwiegian Gem. It's great!
Here are the standouts at sea:
Norwegian Cruise Line provides cushy smoking retreats and cigars sold by the stick from makers including Davidoff, Gurkha, Cohiba and Fuente, as well as some selections by the tin. Lounges are named differently on various ships: the Corona Cigar Club on the Norwegian Gem and Pearl, the Havana Club on the Jade and Dawn, The Smoking Lounge on the Spirit, and The Humidor Cigar Lounge on the Epic, Breakaway and soon-to-debut Getaway.
