I am copying Donna Lee on my answer to this question because if I am incorrect Donna will let me know. 

 The city tour is not planning on stopping and going into the arch or the museum which is underneath the arch.  It will be driving by the arch. 

 If anyone would like to take the time to go back and go up in the arch and visit the museum that would be done on there own time.  The other thing that also might come into play with visiting the arch is the Mississippi river that is now flooding.  I do know that the flood gates are up and the first street next to the river is now underwater and that is why we have to cancel the river boat cruise and dinner and the people that signed up will be getting a check back in there welcome packages for this cancelled event.  If the Mississippi keeps rising it could go as high as the arch steps (which it has done many times in the past years, the l993 flood was the worst I ever saw in St. Louis and the river was past the arch and there was no way of touring it at that time). 

 In short if Nancy wants to tour the arch I would suggest she make the time to do so on her own with her family members (if the flooding does not go that far) and I would also suggest after she does that (it only takes about 2 no more than 3 hours if that long to tour and go up in the arch) I would suggest she goes to the St. Louis Zoo.  The St. Louis Zoo and the San Diego Zoo are probably the 2 best Zoos in the U.S. and the Zoo is on the way back from the arch to the hotel and you can get there on highway 40. I am sure the hotel will have information on both the Arch and the St. Louis Zoo.

 I hope this is helpful.
