RE: London Rocks! (2014 to Present)
The theatres usually open up about 20-30 minutes before show time, so if you go then there will be no line, you can just walk right in, and there still will be plenty of extra seats. Really I've only waited in line for Celtic Fyre, waiting for the theatre to open, but other than that, all the other show venues let you walk right in whenever you want. Other than More Pet Shenanigans, but they usually always open that one 45 minutes, or more before show time. Plus, it's a very, very rare day when any show venue fills up, so never worry about not being able to get a seat.
