We've been on a few cruises during hurricane season. The most memorable was in between Ivan and Jeannie. We weren't even sure when we were heading to Port Canaveral if we would be boarding the ship there as the port was closed, or if we would be being bussed to Miami. We stayed overnight in Port Canaveral, still not knowing. The hotel we stayed at didn't have power, some of it didn't have a roof. It had been flooded, The rooms smelled. We made a run to Walmart and bought deoderizer, bottled water, etc. all the hotels around were in the same shape. we were lucky we had reservations and it was available. The restaurants didn't have water, so they had limited options. We woke up the next morning, and found out that the ship was able to dock, so we got to the port. We were on a 7 day Western Caribbean Cruise. We still lovingly refer to it as our Mystery Cruise. We had to out run Jeanie at every turn, and avoid Ivan.
We didn't get to go to any ports of calls that were scheduled, except Castaway Cay. We were the only ship to make it between Frances and Jeannie hitting it. We ended up going to Nassau, Grand Cayman, St Thomas, and Puerto Rico. We had a few rough nights at sea, but during the day, most of the time, the captain was able to keep us in the sun. Especially on sea days. They try very hard. Even if they have to alter the course, and go alternate routes.
They take the safety of the ship and passengers first. They want to get you where your supposed to go, but they want you to have nice weather as well. In all of the days I've spent on the ships, and we are up to our 10th cruise, that we just finished, we haven't had very many rainy days. And we tend to travel during hurricane season alot.
Enjoy your vacation. I bet your captain will do a great job.
