You know your going on a world cruise when...

• You buy 3 giant tubes of sunscreen, wondering, will this be enough?
• You try on clothing and the sales person says, you could go down a size and you say, "No, I'm going on a world cruise".
• Suddenly elastic waistbands are a feature.
• Your keeping an eye out at Costco for the industrial size bottles of hand sanitizer.
• The question of "Exactly how many bottles of shampoo do I go through in 4 months?" has real meaning.
