Travel 2 is offering savings of up to £856 per couple on its 14-day Argentina & Ecuador tour, which includes a Galapagos Cruise.
It also includes a two-night stay at the recently opened Masphi Lodge, with the next travel date on January 6.
Prices lead in at £5,666 per person based on two sharing when booked by September 30.
The company's Canada, Alaska, Latin America & USA touring product & purchasing manager, Brian Hawe, said: “Mashpi Lodge has recently opened offering a luxury hideaway experience in the heart of an Ecuadorian Cloud forest. It offers the height of luxury in the middle of the jungle and is an ideal combination with a trip to the Galapagos Islands or to the Sacred Valley and Machu Picchu in nearby Peru.
"The Galapagos Islands has some great offers available at the moment for the rest of 2012 and 2013 bookings can be made at 2012 rates with one of our partners, Kleintours. The destination also offers great value for families and couples and is a once in a lifetime experience for those keen on wildlife.
"Costa Rica also continues to be a popular choice and offers a true back to nature experience for everyone. In Buenos Aires we have an exclusive rate at the NH Crillon hotel from now until the end of February.”
