Our 2nd cruise we were supposed to port out of Tampa. However, TS Isaac was quickly coming up the coastline and the swell became large enough the cruise ships could not navigate under the bay bridge. We were all bussed to Canaveral where we ended up sailing out of on time. However, as this was a different route, our entire itinerary was reversed. For those that booked shore excursions through the cruise lines, they were all handled for you. However, my wife and I rarely use the shore excursions and tend to book ourselves directly. A lot of calls were made for us to change schedules and we were 95% successful.
