Why don't shemale escorts give you their hotel room # when you phone from your home for a date?

[dim dom]

Ok, when i phone a shemale escort from my home phone either for the first time or repeated times and i make the appointment for 90 minutes later since i usually live 90 minutes away, they always tell me they will only give me their hotel room number once i arrive to their location and phone them by my cellphone or smartphone. The problem is i don't have a cellphone or smartphone and it is an incovenience for me to find a pay phone on the street to phone them once i arrive. So my question is what reasons would they have not to give me(or any client) their hotel room number 90 minutes before i arrive when i phone them from my home, and only give me their hotel room number once i arrive to their location?
