Do everything Sanddune suggested. Make sure you visit the craftsmen including the glass blower, the candy maker, the bread bakers at Delilahs, the blacksmith, and the furniture makers. Catch a show by the Homestead Pickers. I think even your teens might enjoy it (well…for a few minutes, anyway). SDC is famous for their skillet bowls. I would definitely give one a try. The tree lighting goes off about every half hour (I think). It's pretty cool.
After your first day on park, have a family talk and make a plan for the second day. That way you won't miss anything. Be prepared to stand in long lines. Veterans Weekend is busy, busy, busy!
