I remember this going back to 2005. RCCL diverted a 5 day Bermuda cruise to Canada to avoid a hurricane. And they were up in arms. So they would cancel cruises - people would be up in arms. They wouldn't divert - people would be up in arms because "you put me in danger." My personal favorite was in Oct 2005 after Cat 5 Hurricane Wilma sat over Cozumel for 2 days then hit south Florida, somebody called Royal Caribbean headquarters (in Miami) demanding to know why they hadn't yet been told where their cruise in December was going to be rerouted. We all told them to wait. As it was their cruise wasn't rerouted - it was one of the first back to Cozumel. Then that same person was mad because it wasn't rerouted.

The best advice I have during hurricane season especially is pack your flexibility. The Captain and crew want you to have a good cruise as much as possible. They don't want to put you in harms way. Unless there is major damage from one of the current storms, don't expect any decisions to be made about your cruise until much closer to the cruise. 13 days is a long time during hurricane season. The best place to monitor is to watch your cruiseline's website and make sure you have entered all your contact info in your reservation. If something about your specific sailing comes up, they will notify you via your preferred method (in one case I got it via all methods).
