A ticket aboard Margaritaville's new cruise line can run as low as $100 a person for a 2-night stay. Here's what it's like to set sail on island time.

Many sailings on the line's booking calendar start at around $100 per guest, leaving this frequent cruiser questioning what I was getting myself into.
