Hi mate! Welcome to the forum...
Firstly the allocation of time in hotel reservation girls is about 45min and usually `1` cum per session....
However depends how you connect with the girl, whether she likes you maybe in a way and `IF` she allows you another
shot is virtually up to her. You may also IF you have time is negociate a 2nd shot with the girl and probably extra $$$.
Depends too on how busy the girl is too and sometimes overtime does happen.
If no 2nd shot on offer then you may have to book another session which will be the sum X 2.
As for 141 walk-ups, same thing but probably a better chance as they dont usually work on time slots or appointments.
End of the day treat the girls well and you should be ok.
Happy hunting when you arrive!
