I get it; giant sets can be a giant pain, especially during peak hours on workdays, when the gym is more packed than usual. Monopolizing four different pieces of equipment isn't always possible.
If you find yourself crowded out of your favorite station, just choose a different exercise that utilizes the same target muscles. For instance, if you manage to snag an adjustable bench, but someone beats you to the pull-down machine, just substitute a barbell pull-over. This lets you target your lats while making the bench do double duty.
