This weekend the Carnival Conquest will have a special guest onboard, William Filomena, who is attempting to sail on all 22 Carnival Cruise Lines ships over the course of a year.

 Since starting his journey last fall on the Carnival Spirit, Filomena has sailed on 17 different vessels, most recently the Carnival Fantasy from New Orleans.

The Washington state resident, pictured here with the Carnival Fantasy’s dancers, has quickly become a shipboard celebrity.

Filomena, who will sail on the Carnival Dream’s trans-Atlantic voyage in October, expects to reach his goal when he embarks on an eight-day Carnival Miracle cruise in December.
