5 things you might think are included on a cruise but aren't!

Continental breakfast is usually free on most cruise lines, but order lunch or late night snack, and you're easily paying $5 to $10 more in delivery fees per order.

Most cruise lines let you bring a bottle or two on board sounds great until you try to drink that bottle of wine at dinner. Then there's the $15 to $25 corkage fee per bottle.

They're automatically added to your bill and cost between $15 and $20 per person per day. For a couple on a 7-day cruise, that's $250 plus.

Forget to return your pool towel and you could be paying $25 per towel.
