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.
Clad in brilliant stainless steel, the Gateway Arch rises high above the west bank of the Mississippi River at the spot where St. Louis was founded. Itâs both the tallest man-made monument in the United States and the tallest arch in the world.
