For you solo cruisers looking to skirt that dreaded single supplement, we’ve come across a real deal: International Expeditions is waiving the fee on several sailings in 2012 – translating to a savings of up to $1,749 for cruisers looking to travel by their lonesome. Set off on one of 11 expedition cruises to the Amazon or to the Galapagos on the small-ship cruise line, specialized in nature-themed, wildlife-rich itineraries.

Cruise a classic riverboat, the La Amatista, along the Amazon and indulge in outings like rain forest hikes, piranha fishing, or meeting with a local shaman. Or, opt to island-hop in the Galapagos aboard the 32-passenger M/V Evolution yacht, where whale-watching, snorkeling, and visiting the Charles Darwin Research Center are just a handful of the scheduled activities. Sailing dates in 2012 include select outings in April and August for the Amazon, or in May and October for the Galapagos islands. Amazon cruise rates start at $3,798 for 9 nights and include all excursions, one-night hotel, transfers, some gratuities, and on-board laundry. Galapagos sailings start at $5,098 for 9 nights and include the same, minus the laundry access, with an additional nights' accommodation. www.ieravel.com
