While not officially a podcast cruise we do have a lot of folks signed up for our 2018 Viking Sojourn Med Cruise. As a matter-of-fact we have so many people signed up that we added a few additional podcasters as well - and we may add more as more cruisers sign-up.
Here are the details of that cruise -

So far the podcasters we have on that cruise are:
Pete Werner
John Magi
Kevin Klose
Ryno Clavin
Craig Williams (and Kylie)
As I said this is not an official podcast cruise but with so many people signed up so far we will most likely host something on that cruise. In addition if we add more cruisers we could add more podcasters.
