Only went there once.
If you are claustrophobic, don't. The cart to the top holds 4 and looks big enough for 1, maybe 2.
VERY tight, and rocks and sways all the way up too.
At the top, you get a sight line of St. Loius, which I knew nothing about (agree, yawn).
But the small area was a great place to watch "bend overs" as all windows viewing require it.
(admitted, this could be good or bad, depending on who is there bending).
