Whether you get taken to the room by the WL or you wait for the WL to enter your room makes no difference. What counts is that the service in the end meets your expectations and you and your little friend are on cloud 9 with a huge smile when you leave the premises. This is what counts and not whether a WL takes your hand and escorts you to a room. It is similar to those girls in strip clubs who escort you to the private room. It's so fake! If I have to wait in the room for the girl to enter, I would prefer it this way since it makes me feel she is coming to please me rather than the other way by going to her room which might be her designated room for the whole day.
