RCCL's Allure of the Seas has been experiencing propulsion issues since early October, which has led to shorter port times on it's Eastern Caribbean itineraries due to needing more time to get between Nassau and St. Thomas.
To fix the issue, the ship is going into drydock in the Bahamas on Feb 24, 2014. As a result, the Feb 23rd, sailing has been cancelled.
