Question about free specialty dining

Thinking of booking cruise for 2016 and getting Specialty Dining Package for free. Is the free package for every night of a seven day cruise? Is gratuity included or is 18 per cent gratuity added to our bill at the time of each meal? Thank you

The free dining package is for every night of your cruise. The 18% gratuity is added to your total cost/final payment. No, you do not pay after each meal on the ship.
