I will be going to Barbados in May this year and would like to visit St. Lucia for a week and return to Barbados for my return flight to Toronto. I've found Liat airlines has flight, but I think its a little expensive (about $350US). Also, there may be a ferry ride possible between Barbados and St. Lucia, but I am not able to find any information about it. Can anyone share their experience or information regarding island hopping in the Caribbeans?
