Discovery Cruise Ship to Freeport question

[zuzanne]

We are going to Freeport, GB in Sept. on the Discovery Cruise Ship. We will take the boat over spend the week on the Island and then take the boat back. We would like to take our dive gear with us. Has anyone done this that could give me some advice on how to pack our gear for this type of trip. We will not have a cabin so it all gets stored in the ships cargo area. We have never been on a cruise ship before so not sure what to expect. Its about a 5 hour crossing from Fort Lauderdale to Freeport.
