I'd would actually argue that reading the script beforehand has its advantages, especially for people who are unfamiliar with the source material:
The script, I'm sorry to say, is extremely flawed. While some may disagree, that seems to be the general consensus. Lots of bizarre twists and turns, lots of clunky dialogues and lazy jokes, etc. What makes the show so fantastic is the physical production. If you're already familiar with the script beforehand, the spotty writing is less likely to taint your experience, because you will be prepared for it, and you'll instead be focused on the production.
Also, reading the script can heighten the anticipation for the show, because the script contains stage-directions of what happens, but they do not reveal HOW they portray it onstage. Since the stagecraft is one of the main joys of this production, you'll go in eager to find out how each bit of magic is portrayed.
Furthermore, if you're worried about following the story and characters - as I expect you would be, being unfamiliar with the original material - reading it beforehand can give you time to clear up any confusion you may have.
