Crystal Cruises, the #1 large-ship cruise line in our annual World’s Best Awards since 1996, is re-introducing the idea of stand-by travel on five of their sailings in May and June. The potential savings from the brochure price are a mind-boggling 70%, bringing the cost of a 12-day cruise to $2,995, or $250 a day.

The itineraries available for standby are pretty exciting: three 12-day Alaska cruise out of San Francisco, an 11-day Scandinavia and Russia trip (Hamburg to Stockholm); and a 14-day North Cape/Arctic Circle cruise (Copenhagen to Stockholm).

The small print: The discounted fares are cruise-only and don’t include the shipboard credits or two-for-one pricing or airfare that Crystal passengers usually enjoy. The standby status requires a $500 deposit and you’ll find out whether you’re on the passenger list no earlier than 45 days before the cruise embarks.

If you’re ever wanted to run away to sea in high-style, here’s your opportunity. For more information, please visit Crystal Cruises, or call (888) 799-4625.
