Pay for their dinner at Victoria & Albert or plan a surprise vow renewal at GF or on the beach at the Poly.

I'd say a nice meal at your favorite WDW restaurant followed by an Illuminations Cruise or Wishes Cruise. They are both memorable and a good way to allow the entire family to celebrate in a special fashion. :)
