It's definitely worth the effort. The good thing about the Music Box theatre is that (for the orchestra, anyway) there aren't any bad seats, with the exception of the first row. Unless you're over 6 feet tall. If there aren't any non-premium seats left, you could try a line sitting service.
If you're open to other shows, Great Comet is pretty entertaining. Josh Groban will have left the show by August, but that shouldn't make much of a difference. It's worth it to go just to watch the conductor. I've also heard really good things about Come From Away. War Paint is worth it just to see Patti Lupone in person.
