Subleasing vs. Renting Hourly: What's Better?

You've been renting hourly for a year. You're tired of hauling your speaker. Is it time to sign a monthly sublease? Let's weigh the pros and cons.
The Sublease Model
Pros: You can leave your mat there. You get "your" time slot forever. You feel "official."
Cons: You pay whether you teach or not. If you go on vacation for 2 weeks, you lose money. You are often responsible for cleaning.
The Hourly Model (Studio Planner)
Pros: Pay-as-you-go. If a class has low enrollment, cancel it and pay nothing (subject to policy). Scale up during busy seasons, scale down in summer.
Cons: Setup/teardown time. Variable availability.
The Verdict
Unless you are teaching 10+ hours a week in the same room, hourly almost always wins on math. Subleases only make sense when you hit "utilization saturation"—where the hourly cost exceeds the monthly block rate.
