Cruiseone.com is a resource for cruise sellers that works very much in the same way than Travelocity, searching for the cheapest cruise offers by date, company, schedule or destination.
The idea behind the site is to connect prospective cruise customers with cruise dealers near to them, and thus assist the growth of the travel agents industry. When looking into purchasing a cruise ticket, you will be asked to select prospective dates and place of residence and age, in order to see if you qualify for special discounts. The site also includes useful information and advice on insurance and travel requirements, like visas and passports. At Cruiseone.com you will also find cruise, line and ship reviews and pictures by travel industry professionals, so you can decide what is the best plan for you, plus there are recommended seashore tours and advice on which cruise to take depending on age, occasion or size of party.
