Worth considering? not really.  Every hobbyists participates at a level of comfort that works for them. If you want to sneak out the stairwell, that's fine if it  makes you comfortable go for it. But I agree with sweetnicole, way over thinking.

My advice, enter and leave the hotel thru the lobby, act with confidence and look like you belong.

been to job interviews in hotels before that lasted about an hour.  That's my story and I'm sticking to it.

check in time. not as noticeable when there is a crowd at the front desk.

Most of the time i notice the clerk at desk is busy when I walk in anyway(they recognize someone entered but they don't look up)

thereare two hotels i've met ladiesat where the elevators were seperate from the desk and you could walk in and go right up w/o being noticed.

act like you belong there, and few will notice you.  It is also important to know ahead of time where the stairs or elevators are located so that you do not appear lost and attract unnecessary attention.  I have never had a problem exiting thru the lobby, for all anyone knows, you are guest going out to run an errand or some sort of touristy thing (if you're in a tourist area).

They don't know that you aren't coming back...

I often do the same.  Yes, there are hallway cameras, but most hotels that have this type of business going on already know it.  
When I have them come to me, I always identify a side door and tell them I'll meet them there and let them in.  Since they don't then know your room number, if someone shows up that isn't as described, or seems to have someone else following them in, you can not open the door - and generally, I'm able to get a window view of the entrance so I can see what's going on.  
It doesn't happen often, but there are some out there looking to rip you off/rob you.  And when you think about it, what a good scam.  Who's going to report being robbed by a prostitute?
