I was speaking about storage aboard before my cruise and I wanted to give you guys a review on what I had done.
I bought 4 dry bags from Walmart. They were pretty cheap. 3 were medium sized and the other was a bit larger.
When I packed for the trip I organized clothing by which dry bag I placed them in. I was able to store the bags underneath the settee on the starboard side. Here is a picture of it: http://i296.photobucket.com/albums/mm199/HeaveToo/Dry%20bags_zpsetbnaa4i.jpg
This solution worked incredibly well. I didn't have to worry if any water found its way into the storage area and they fit fine. It wasn't a big deal to get them out of storage when I needed clothes. I am going to stick with it and I am pleased with how well these bags worked.
