Turns out 2015 is a big year for the cruising industry with two major lines celebrating milestone birthdays.
In addition to Cunard, which fetes its 175th anniversary next year, Princess Cruises will also mark its 50th anniversary and has launched a special commemorative itinerary to Mexico that will retrace its maiden journey with ports of call to Puerto Vallarta, Mazatlan and Manzanillo.
New destinations like La Paz and Loreto have also been added.
The 14-day cruise will depart December 3 -- 50 years to the day after the line's original ship, the Princess Patricia, set sail in 1965.
This time, guests will board the Pacific Princess.
After 50 years, Princess Cruises is now the third largest cruise line in the world.
Next year marks another major milestone in the cruising industry, as Cunard will fete its 175th anniversary with a series of special events. The British luxury liner made its mark when it became the first passenger cruise line to circumnavigate the globe in 1922.
In May of 2015, the British port city of Southampton will host a major celebration when three of Cunard's luxury liners reunite in a "Cunard Royal Rendez-Vous," which promises to be an impressive and grandiose spectacle.
