I offer a range of bookings and have discovered I do seem to do well with longer bookings with clients who like to talk.
Like fallen angel I used to think "Hang on this guy is paying a lot of money to just chat", but they told me that is what they want - sometimes they physically could not have sex for a long time, and/or wanted the intimacy, cuddling, kissing, talking. I am not going to argue with this and have some really nice bookings. I also find one hour bookings seem really short and to some extent easier because I have the stamina built from 2, 3, 4, 6, 16 hour bookings. When I say stamina I mean ability to be with the person, be with them, pay them attention.
I need to keep footfall down, almost always been that way the longer bookings are often well away from my base location with clients who are from other parts of the country so it's much better discretion-wise. Also stayed in some really nice hotels, some I would return to for personal reasons. Given I live in the sticks I try to fit in visits or use of facilities I wouldn't usually be able to access at home.
I do however appreciate shorter bookings too and can understand why they are a preference for others.
