Cool Paul!

http://marketerscruise.com/ ... and search "marketer cruise" for other marketing vertical cruises. Steal some ideas from them of their setup, pitch, pricing, speakers etc.

And... of course... topics.

The reality is the majority who go on a "business cruise" like this aren't there for the topics. They are going because it's a great vacay opp, fun in the sun and Networking.

In my opinion, your topics holds very little weight in the overall picture.

Instead, personally, I'd look at how you can add maximum networking value and pitch THAT angle more.
