No it is not necessary to call us, inform us or make advance reservation until the moment you are in hotel or place whereby you want us to deliver. Please do not call to ask what stock is available when you are not ready to order. All the information is on the website and you need to read through. The main objective of calling our booking line is to place order. You are supposed to be prepared with what you want and know the price. If you have contacted the girl you wish to order then please be on time when you ask us to reserve the girl.
