With the promotion, all-inclusive fares start at $2,299pp with savings up to $4,000pp for an ocean view stateroom.
The offer allows solo guests to sample all of Crystal Symphony’s luxury amenities at double occupancy rates without the supplemental fee typically charged to solo travelers.
Carmen Roig, Crystal’s senior vice president of marketing and sales, said solo travelers are an "important segment" for the line.
"We wanted to provide our solo ocean guests with the same opportunity to take advantage of the incredible value and convenience offered by this promotion," Roig added.
The promotion is available on Crystal Symphony sailings departing from six homeports in North America and Europe.
It includes seven-night Caribbean voyages from Miami and San Juan with departures in January through March 2022 and seven, eight and 10-night Mediterranean sailings from Lisbon, Venice, London and Monte Carlo.
