Wilde may not have stayed overnight in Springfield, because after the lecture, he traveled night and day on February 27/28 arriving at the Grand Pacific Hotel in Chicago, IL, before beginning the next leg of his tour in Dubuque, IA, on March 1. (This was the next day as 1882 was not a leap year).
However, according to the Lincoln Library in 1911 citing the Illinois State Register of February 27, 1882 (not found) when reporting to the early Wilde researcher R. B. Glaenzer, Wilde stayed at the Leland Hotel. 
It is quite possible that Wilde used the Leand Hotel as his base without actually staying overnight.
