Hi Christie!
Well first, congratulations on your upcoming wedding, honeymoon, and married life! There's magic at Disney, but nothing is more magical than spending every day with your Forever. As it is with my wife, she is my Happily Ever After, so cheers to you...
You certainly won't lose any of your park admissions if you dine, say, outside of the parks on any given day. When we stay for a week, we generally try to do a "no park" day just to enjoy the resort with our children. We use our meal credits at the resort, and still have whatever park tickets remaining even if we didn't visit a park that day.
Have a wonderful time on your honeymoon at Disney!
