One of the major benefits of being an author is being able to speak on cruises.
The first cruise I went on was because a speaker had to cancel at the last minute and I was whisked away with 3 days notice to Miami where I caught a 10-day cruise to Ocho Rios, Jamaica, Panama, Cozemal and several ports.
I spoke one hour each of 4 days and had audiences from 10 to 2,500! The topic was about communications and I think I was up against Bingo the day there was only 10. But the activities director doesn’t mind how many people attend, as speakers, we’re part of the on board entertainment while at sea.
