I agree that it's often easy enough to find a good seat without the package, but the reason I like to do the package anyway is that it makes it so much easier to get out at the end of the show. It's a huge crush of people, but if you're in the reserved section, you'll be out before 90% of them, which means you'll be hitting the buses or trams before 90% of them, too. To me, this fact alone makes it worth buying the package.
