Send a text in the morning about ten or whatever confirming the appointment.
Send another confirmatory, short text about say 35 minutes before the appointment time. You will probably be calling her directly a couple of minutes before appointment, from general nearby location you have been given.
When booking appointments, if not told how to confirm, ask or suggest to the escort the above.
Many escorts will not hold an appointment if you do not confirm a booking that may be hours away.
