Are you serious? Not caring about rules and thinking they don't apply to you mean the same thing in this case - entitlement. "I won't cause any problems, so I don't have to abide by the rules." There are plenty of people who use selfie sticks safely and politely, but they're still not allowed to bring them into the park. You can't just pick and choose what rules you have to follow.
Yes you can. You totally can.
It's called not being a robot.
This can have a snowball effect. People might see you swimming, think they're "entitled" to do the same even if it's after hours, and then there might be actual problems.
Maybe, maybe not. I'm willing to take that risk.
More to the point, if I come back from the parks at 1AM and see people swimming in the pools and not bothering anybody I'm either going to join them or mind my own business.
If, on the other hand, I'm woken up at 1AM by some noisy kids in the pool, you can totally bet I'm calling the front desk.
