This fall, agents selling three or more staterooms on any of Crystal Cruises' four 2010 New England/Canada cruises will have the rare opportunity to enjoy the line's luxurious, butler-serviced Penthouse accommodations - for free.

Departing September 19, September 30, October 11 and October 22, all voyages feature overnight stays in Montréal and either Boston or New York, plus visits to Newport, Rhode Island; Saint John, New Brunswick; Halifax, Nova Scotia; Québec City, Québec and either Bar Harbor or Portland, Maine. Eligible agent voyages for two are October 11 and 22, sailing between New York and Montreal.

Strong travel incentives for guests provide sweet selling tools:

•  Promotional Two-for-One cruise fares;

•  Free air transportation from more than 20 North American gateways;

•  $500 per person 'All Inclusive - As you Wish' shipboard credits; and

•  Crystal Family Memories program offering perks for groups of six or 10.

"Promotions like Crystal's Sell Three, Sail Free offer make the selling process more compelling," says Bill Smith, senior vice president, sales and marketing. "It's always a great incentive to enjoy the quintessential Crystal Experience by simply selling three staterooms, but the added bonus of sailing in Penthouse accommodations allows agents to speak to the finer nuances firsthand for future opportunities to sell up."

Following a $25 million drydock last fall, the award-winning Crystal Symphony boasts completely transformed Crystal Penthouses, Lido Café and pool areas, elegantly redesigned Penthouses and Prego Italian restaurant, and dozens of behind-the-scenes improvements.
