I'll actually answer your question instead of offering some smart ass remarks.
The tour is pretty identical to the Broadway/Sit Down productions.
Here are a list of differences in set
The balconies (i.e. Morribles's Speech, Tin Man's speech) are not extended out to the house...instead they are brought out onto the stage (automation) on both SR and SL
In "No Good Deed" there is no elevator lift that brings her up through the floor...instead she runs on from SL while a small bookstand rises up from the floor at the front of the stage with the book on it and she runs to it.
The Broadway production has 4 large clock towers that move on and off...the tour has only 2 large towers and during "Defying Gravity" two small ones come on with the larger ones.
The accent in "Defying Gravity" is much faster then Broadway
Depending on the theater,(SPOILER)The effect of Elphaba coming up through the trap door at the end of the show is different. In theaters with a trap door...its the same as Broadway, in theaters without a trap door, they bring on a prop that looks like a well...with a false trap door by it...Fiyero opens it, and she ducks from behind the well to make it look like she came up through the floor.
And thats really it...the set is pretty much the same, the automation (On the first tour) is the same (the second tour has automation just not as much as the others) the tracks are much different but thats not going to disturb the look of the show...hope ya enjoy
