Room only: she is never met out
Room only means she comes to your hotel room or apartment and nowhere else, never to a restaurant, bar or theatre, and never joins any part of the evening.
This site is built around a night out, which makes one line especially important to draw clearly. She is never met at a restaurant, a bar, a club, a theatre foyer or a street corner, and she never joins any part of the evening. There is no drink together first, no walk back side by side, no waiting in a lobby for a guest who is still at the table. The house arranges a session in a private room and nothing more.
Why the line is fixed
A booking made on the way back is sometimes read as an invitation to combine the two halves of the evening. It is not, and the reason is simple. The session happens in private, in the room you are staying in, and the evening before it is yours alone. Keeping them apart is what lets the timing work: you finish the evening at your own pace, head home, and she arrives at a door you are already behind.
What it means for the plan
Every piece of timing advice on this site follows from this entry. Be back first. Plan your walk home honestly. Allow ten minutes in the room. If the lift needs a keycard, you may go down to let her in, and that is the only time you meet anywhere but at your own door.
The addresses that qualify
A hotel room or a rented apartment in central Amsterdam, or a room at a Schiphol airport hotel arranged separately with her journey time agreed first. Nothing is arranged in a public place, and nothing outside the city and the airport. See outcall for the rest.
