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.
The Old Courthouse is built on land originally deeded by St. Louis founder Auguste Chouteau. It marks the location over which the arch reaches. Its dome was built during the American Civil War and is similar to the dome on the United States Capitol which was also built during the Civil War.
