Celebrity Cruises is offering a wide range of Caribbean sailings this winter, and a new booking promotion aims to sweeten the deal. Now through Aug. 14, 2010, guests who book select Caribbean cruises in certain staterooms can receive up to a $200 onboard credit per stateroom.

The promotion applies to Caribbean cruises of seven nights or longer sailing between October 2010 and April 2011 – including all three of Celebrity’s Solstice-class ships. Guests who book veranda staterooms, Concierge Class staterooms, AquaClass staterooms (available only on Solstice-class ships) and suites now through Aug. 14, 2010, can receive an onboard credit in the amount of $100 per veranda stateroom, $150 per Concierge Class stateroom, $150 per AquaClass stateroom (available only on Solstice-class ships) and $200 per suite.

Celebrity’s Caribbean destinations include St. Johns, Antigua; Oranjestad, Aruba; St. George’s, Grenada; Willemstad, Curacao; Scarborough, Tobago and San Juan, Puerto Rico. Rates for a veranda stateroom start at US$799 per person for a seven-night cruise and US$999 per person for longer sailings, based on double occupancy and excluding taxes and fees. Celebrity Cruises reserves the right to impose a fuel supplement of up to $10 per person per day. Guests can apply their onboard credit toward reservations at Celebrity Cruises’ specialty restaurants, such as Murano, which serves a blend of classic and modern Continental cuisine. Cruisers can also spend their onboard credit on the expanded selections of beverage packages, spa treatments and shore excursions. Onboard credit is quoted in US Dollars, is not redeemable for cash, and will expire at 10 pm on the last night of the cruise.
