Christine Roberts, VP, convention & group sales, Greater Fort Lauderdale CVB, told CMW that the safety of its residents and visitors is of paramount importance.
"Hurricane Matthew was a large and potentially dangerous hurricane that was forecast to impact South Florida on Thursday, 6 October. Starting early in the week, the Greater Fort Lauderdale Convention & Visitors Bureau monitored the storm and was in close communication with hotels, planners, and the Broward County Convention Center to determine the best course of action with each group or event. We polled our hotels to ascertain available inventory in the area.
"Preventatively, a number of local events were cancelled for the weekend, guests (group and otherwise) were advised to depart earlier than anticipated, or in some cases groups were postponed entirely. For those that were unable to depart the area, guests were given the opportunity to remain in their hotel or voluntarily be relocated to hotels further west from the beach and low lying areas."
The airports in Florida have now reopened, and officials are checking on the well-being of guests and communicating with planners with groups scheduled to arrive to advise them that our resorts and area have resumed normal business operations.
