Known for its plush all-suite ships, Crystal Cruises will let you book a trip with no money down, now through January 5, 2021. Until January 6, 2021, you’ll also enjoy “Book Now Savings,” which offer up to $9,000 per suite in savings. Crystal River Cruises also offers a “best available suite” upgrade for all 2021 sailings. Feel like really leaning into a cruise for 2021? “Grand Journeys”—which range from 14 to 100 nights—are an extra five percent off at the moment.
