"Hurtigruten makes cruising the Galapagos Islands more affordable by waiving the single supplement on several of its Galapagos cruises. Hurtigruten Galapagos cruises range from seven to 14 days in length and take place on the MS Santa Cruz II, a ship that comes equipped with panga boats, kayaks, snorkeling gear, paddleboards, and a glass-bottom boat for viewing marine life. The ship carries a maximum of 90 passengers, and its operations are carbon-neutral. There’s a small gym and a hot tub on board. Regular prices start around $8,500 for a one-week cruise. Look for sales to bring your price down even further."
