Maybe downsize it a little for the test run? A trailer park in Florida with a swimming pool.
Given the incidence there seems to be of mass food poisoning and outbreaks of disease, I remain less than convinced of the merits of cruises. Add to that the feted instances of cruise liners breaking down and drifting without aircon or power and appeal diminishes even further. To top it off there seem to be a lot of cruises where the in-house entertainment seems to consist, at least in part of an Eagles or Coldplay tribute band. On the whole drifting, rudderless and ablaze, in shark infested waters seems preferable to that.
