We're planning on stopping at Gettysburg for one full day before our trip to DC. Plan is to do the Visitor's Center as soon as it opens, then audio CD tour in and out of our car for the battlefield, snack, then Eisenhower house, then dinner at Dobbins House, then check into hotel at night. Is this way too rushed for a family of 4 (kids 8 and 10)? Would you make changes to that itinerary based on things a 10 year old history buff would want to see, have the stamina for? Thanks!
