We took the grandparents on the Staten Island Ferry today. I keep showing them the countryside version of NYC because that's what I'm attracted to. I promise to show them Time Square or something crazy before they leave.
My Tip for the Staten Island Ferry: For the best views of the Statue of Liberty, as soon as you enter the ferry, stay put. Don't walk up the higher levels or deep into the boat. Stay at the boat's enterence. Everyone will pass you by to the higher levels and deep into the boat. You'll be left standing alone with great views! Once on Staten Island, we stopped by the September 11th Memorial, had a picnic and threw rocks in the water. Then took the boat back. Simple beautiful hot day.
