• I'm a former cruise director, and I've seen many people make mistakes on their first cruise.
• Research your cruise line, preferred cabin type, and destinations before booking anything.  
• Don't fly into your departure city the day of your cruise, and prepare for changing weather.

I'm a former cruise director with over a decade of experience in the industry. Now, I live on cruise ships part-time with my husband.
