We took our two girls, 2 and 4, on The Constitutional, a walking tour of historic Philadelphia. We explained to them that during our vacation, we would be doing some things for Mommy and Daddy, and some things for them and therefore no whinning would be allowed. Surprisingly, they liked the tour! It took us all day to complete it and we were all tired afterward! Wear comfortable shoes, bring snacks and drinks, and definately the stroller for little ones. The tour starts at the National Constitution Center, but we went to the Independence Visitor Center first so that we could get our tickets. Afterwards, we just followed the map and visisted every site. Along the way, there were things and people to keep the kids entertained that I believe where provided by Once Upon a Nation. They had people dressed like Colonial men and women, games and toys that colonial kids played with, and many other demontrations that were hands-on. It was a great learning experience for the girls and believe it or not, a year later, they still remember what they had learned from the tour. During the tour we stopped to eat lunch at The City Tavern. It was pricey, but the food was good and the service was wonderful.
