Absolutely must see attraction in St Louis; the wait can be long some days but it is worth it.
I did not imagine that the structure of the arch would be that impressive. The service is well organized, and the staff is helpful and courteous.
It requires a minimum of three hours of your time in somewhat busy visit day.
Plan about 30 minutes or less for the museum inside the arch before the ride.
