I am pretty sure Ive used Grandeur once quite recently. I chose to see Jessica for 1 hour booking (who is no longer on there) and she said that it was only a one pop session - however I charmed my way into a second serving. A bit risky if the charm didnt work on another girl - so seems like the one pop is this agencies policy which is a bit rubbish for an hours booking.
Oh and by the way all the photos are 100% fake
