I would cancel the appt. with some excuse.  Anytime you have a bad feeling about something like this, you should trust your gut.  I too see too many unusual issues with this appointment.

It's better to use her hotel room, then you don't leave paper & credit card trail.  (Her rate will likely be the same but you'll have the added room cost.)  I doubt she'll want to dress for public view to go from one room to another.  You had one good appointment if I read your post correctly, so she's ok.  

Hotels are fine for appointments...  single entrance with traffic to & from all rooms mingling through a common entrance...  near impossible to track easily.  

NOT MOTELS with outside doors to each room...  easy to track traffic to an individual room.  

If things calm down then do the appointment.  If it's just too confusing then rebook for a later date, when she'll be settled & unrushed.  It's about what you feel comfortable with.  If you're stressed, you may have trouble relaxing.

There is nothing you can ask since you already know that LE will lie to you.

Either you trust her after the 1st meeting or you don't.

Things happen to hot young girls, and there can be some drama. It's part of their appeal.
