I can do 6am  but I only have incall 1day a week  

But I'm a morning person in general, so the early dates don't bother me. It's the 11p-4a ones that I'd be less likely to take, since that's when the drunks and tweakers tend to abound.

I don't mind them as long as there's a coffeemaker in my hotel room, haha.

Can only do with advance notice and preferably when visiting the burbs. For the right person I will do it from my Chicago Incall,. The issue is sometimes when ppl request early sessions they flake out. I get frustrated because I made great effort to accommodate them

I have a feeling with pretty much anyone you are going to be looking for a long time.  Letting me know the night before and completing prescreening prior to that night before set up is required.  Anything less and well, the lady is taking chances because you just can't verify someone quickly at night nor 1st thing in the AM.  Do you really want to see someone and do the intimate things you do with someone who just lets anyone shove it where ever.  It does pay to be safe and selective..  Take care and play safe.

I don't have a very typical sleep cycle, so I could possibly do very early mornings. As usual, I prefer a good two day notice for appointments whenever possible. :

I once lived in a place with a 24-hour red light district. It was pretty awesome to stop there on my way to work, have a quickie with my favorite regular, and get to work on time.  

I was very grateful to my regular for being a morning person. She was pretty grateful to see me roll up at 6:30, because the district was pretty dead at that time.

when traveling, I'll frequently see a lovely person in the evening...we'll get very acquainted and very comfortable together.  I'll ask and generally get a positive response to a wake-up call before my meetings, etc.  Very nice way to start the day!
