With responses like that I wonder why anyone bothers posting questions.
Thank you so much for your help!
"It depends" will be the reliable answer.
Many are bait and switch, while some are not. As you rightly ask, only confirmation from someone who has been is useful to you and even then may be short-lived given the girls are often on rotation.

Good luck.
