Pin code question

[mymainmouse]

My mom received the Free dining or 35 % pin in the mail. The Free dining says "Free Disney Dining plan when you purchase a non-discounted 4 night/ 5 day Walt disney travel company and theme park ticket package at select Moderate, Deluxe and Disney deluxe villa resort hotels." Then it gives the dates. Does this pin have to be used on a 4 night stay or can it be used for fewer days? We are thinking about tacking 3 days on to our cruise vacation and staying at Disney world but we dont have anymore time than that. I would really like to go but just cant justify taking my kids out of school anymore than they already will be. Free dining is a good deal. My mom is going with us btw.

For anyone else who might have wondered, the pin code that my mom received had a free dining pin and could only be used on a 4 night/5 day or more package. I called Disney reservations and asked.
