Oceania Cruises’ Winter Collection, featuring voyages from September 2012 through May 2013, goes on sale today.

The cruise schedule includes 21 all-new “grand” voyages ranging from 23 to 71 days, as well as Caribbean and Panama Canal cruises onboard the line’s new 1,250-guest Riviera. With advance booking savings, seven-day cruises are priced from just $1,499 per guest, including round-trip air.

“Our loyal repeaters and first-time guests alike will appreciate the depth and diversity of our 2012-2013 Winter Collection,” stated Bruce J. Himelstein, Oceania Cruises’ president. “With the addition of Riviera to our fleet, Oceania Cruises will expand its presence in every region of the world offering new and intriguing destinations to delight discriminating travelers.”

Oceania Cruises’ 684-guest Regatta will again offer her foliage cruises in September and October before cruising to the Caribbean and South America. New ports include Boston and Portland, Maine.

After a 25-day Enchanted Amazon (departing Nov. 2, 2012) cruise from New York, Regatta offers a seven-day Caribbean Interlude (departing Nov. 27, 2012) cruise before operating Panama Canal cruises between Miami and Los Angeles (beginning Dec. 4, 2012).

A 30-day South American Explorer (departing Jan. 23, 2013) itinerary from Lima to Rio de Janeiro showcases the very best of South America. From Rio, Regatta reprises her 12-day Radiant Rhythms (beginning Feb. 22, 2012) cruises between Rio and Buenos Aires before heading to Europe for summer 2013.

Riviera – a sister ship to the Marina – will make her North American debut with a winter season of Caribbean and Panama Canal cruises beginning with Idyllic Isles (departing Nov. 29, 2012). The new itineraries venture deeper into the Caribbean; a 14-day Island Holiday (departing Dec. 20, 2012), for example, will include stops at Kingstown, St. Vincent and Philipsburg, all new ports for Oceania Cruises

Oceania Cruises’ maiden season sailing the South Seas was a success, so Marina will replace the smaller Regatta on cruises to Australia, New Zealand and the South Pacific. The 20-day Ancient Legends (departing Dec. 27, 2012) journey to Polynesia via South America will visit such exotic outposts as Robinson Crusoe, Easter and Pitcairn islands and Fakarava in French Polynesia. Following her Down Under cruises, Regatta sails a 20-day Grand Panama Canal (departing May 6, 2013) cruise from Lima to New York. She then heads to Southampton on a 16-day Viking Passage (departing May 26, 2013) via New England, Canada and Ireland.

The 684-guest Nautica will return to the mysterious and magical continents of Africa and Asia. For example, the 17-day Asian Treasures itinerary (departing Feb. 4, 2013) sails from Singapore to Hong Kong followed by the 17-day Empires & Dynasties (departing Feb. 21, 2013) sailing from Hong Kong to Beijing. Sands & Safaris (departing Jan. 5, 2013), is a 30-day cruise from Cape Town to Singapore via the Seychelles, Sri Lanka and Maldives.
