I find that the Inez/Monas site is pretty accurate. but like others have said, shit happens. sometimes a lady isnt feeling well, or steps out of the house (like to doctor or errands), or isnt up/scheduled yet. also hard to keep a site updated to the min.
I will text Louis the day I am heading out and/or when I arrive. also stop in and see Anna/Peter to see exactly what is going on in the houses.
even still, I had an appt get cancelled. well moved to the next day. she apologized as she wasn't feeling well, and was happy that I was able to meet her the next day and had a great party.
I try to have a backup plan in place. I know for some it doesn't work that well. luckily for me I don't have a super specific type. so I come into town with a couple of girls I would like to see, and try not to hyperfixate on seeing a specific girl. Mila is a great lady, and I would say that I would probably be disappointed if I didn't get to spend some time with her.
