I’ve gone both routes. I’ve scheduled appointments, came in at the appointed time and had great times with these ladies. Other times I’ve DM/twitter a lady and told her ahead of time I would be in on a certain day and time. Lately I come in the day before our party and meet her in the bar. I like that we can get to know each other before hand. This way its not a rush to get back to her room to start the negotiations process and we have a little knowledge of each other.
