I realize the wording is a little rough so let me see if I can clarify it.
Disney offers packages with tickets and packages with food and tickets. When they offer a package the easiest way to get an idea of the price is to figure the room with tickets only and see what the total is. If the toatl comes out to the quote you are given with the food that means the food is free. You have to purchase the tickets in order to get the dining no matter what so you will see the difference in price. If you are looking at this ad, the key word is and. The phrasing says $63 per person for room, tickets AND free dining for a family of 4. So if you have a couple instead it is going to be higher in price but the food is till free. If you multiply the number of days by how much the meal plan is you will se how much you save per person.
