Agents making two new bookings with Crystal Cruises can earn a sailing for themselves in a new sales incentive.

Bookings must be made for any Mediterranean departure in 2012 by Crystal Serenity.

The ‘Sell 2 Sail Free’ incentive applies to bookings made until January 31, and the free cruise is valid on any of 50 departures next year.

The ultra-luxury line claimed the promotion was its “most generous” booking incentive ever.

UK sales and marketing director Ray Steward said: “Crystal’s 2012 programme is incredibly attractive with all-inclusive pricing, free flights and prices from as little as £2,141 per person so I’m confident that agents will be able to take advantage of ‘Sell 2 Sail Free’ and get on board with us next year.”
