How long do people usually spend here?

expect to spend 3-6 hours there

It depends on why you're there, but yeah...unfortunately, 3-6hrs is a reasonable estimate on average if you're not obviously bleeding to death upon check-in. BUT!! Sunday IS usually the best day to go time-wise, because most people are trying to hold out until Monday when drs offices will be open again...so, you might be able to get in & out in just 2hrs if you're lucky. (Esp. if you go before it gets later into the night, after the urgent care clinics are all closed.) Good luck & hope you start feeling better soon!
