Here is more info on Silver add on from Mousesavers
The Silver Plan costs $68/night for adults and juniors (ages 10 and up) and $35/night for children (3-9). Each person gets 2 "Magical Wishes" per night, which can be used for a variety of meals and entertainment options.
However, all of the "Magical Wishes" for everyone in your party are "pooled," so each individual doesn't have to use up his or her own wishes. For instance, if you have a family of 4 and stay for 5 nights, you'll have a "pool" of 40 wishes to use. So if you have kids included in your package, you may want to think about the value of your wishes based on the average price overall. In this example, if you had 2 adults and 2 kids for 5 nights, the cost is $68 + $68 + $35 + $35 x 5 nights = $1030, divided by 40 wishes, for an average of $25.75 per wish.
Generally speaking, it's not a good use of wishes to "spend" them on meals or admissions for kids. Even though you're paying less for the kids' wishes, the value of kids' meals and admissions is a lot lower than those for adults. So try to use the wishes for the adult meals and admissions. At meals, just tell your server what you're doing.
Also, you can use your "Magical Wishes" whenever you want during the vacation. If you have 16 wishes and you want to use them all the first day, you can do that! Just be sure to use them all up, because they expire at midnight on the day you check out of your hotel.
