With the silver plan, you get two wishes per person per night. So, if there are two of you staying for five nights, you would have a total of 20 wishes to use.
Yes, you could use your wishes for a character breakfast and character dinner each day if you wanted to, although if you did that, you would wind up paying more for the meals with wishes then if you are if you paid as you went. When I did the silver plan, it cost me $69 for two wishes. With tax and tip, a character breakfast would have been around $25, and a charater dinner, would have been around $30, so I would have spent $69 when I could have paid cash for $55. Make sense?
Wishes can be used for things other than dining--it can be used for recreation, spa treatments, and tours. Use your wishes carefully to make sure you get your money's worth.
