The Statue of Liberty
I bought our tickets on line in February for an August trip. There was an option to spend an extra $7 per person for a "Crown Ticket". Wow! There were hundreds of people standing in line in the heat to get inspected before climbing onto the pedestal of the statue. We were checked out in a small building and led like VIPs right past everybody else and into the stairell to the crown. We had the crown to ourselves for about 20 minutes with just one park ranger to keep an eye on us and answer questions. What a deal! See if you can do the same! Planning ahead has helped us so much.
