The short answer is no! Every cruise has a stated departure time. You can board the boat up to 30–45 minutes in advance of departure time. Every one of our cruises must leave at its scheduled departure time. We urge you to arrive early and to leave in plenty of time for traffic and parking. The Florida area can get very congested, and there is occasional construction traffic. If you miss the boat for any reason, there are no refunds or rescheduling, so please don't miss the boat.
