It's an amazing monument. Order tickets online to avoid Iines. Be prepared to do the equivalent of an airline security point checkin (no metal/belts/phones). No strollers allowed at the top of the arch, but they have a place to park them. The museum has been completely redone (opened July, 2018) and is very interactive (touch screens, lots of videos, etc.). The arch is a must do, if you're in St. Louis!
