Every hotel we have stayed in the US requires you to be 21 to check in and certainly with a 16 year old (unless as the poster said,you are both female) would absolutely not be allowed..If someone over 21 checked you in,it might be allowed but call the hotel and make sure.
Known by many as the St. Louis Arch or simply âThe Arch, this structure's actual name is the Gateway Arch. As part of the Jefferson National Expansion Memorial, the Gateway Arch stands as a monument to the westward expansion of the United States that occurred after Thomas Jefferson completed the Louisiana Purchase.
In St. Louis, The Old Court house and the gateway arch are like bookends, not just of a large historic and civic area, but of history itself. work is already underway to prepare the arch and st. louis for another 50 years of tourism and progress, both economic and social.
