I am thinking you must be writing from the US - right? Not the same circumstances here as there are once you cross the border. In the US... you can find ladies who will see you at your hotel without information, but you might reconsider since I believe it is a bigger risk to reveal your activities to a hotel clerk than it is to reveal your name to an escort (especially one who is well reviewed and respected)... in Montreal, different ideas apply. If you are not comfortable sharing your name rent a 4 hour room and call an agency. If you plan to see indy girls here, you may have to share something... I am not sure, I only know what I need to feel comfortable, but with an agency, here, they don't need all that from you.
ARRGGGG!!! So many questions, so little effort looking for answers himself first!!
Do some effort man! Most of what you're asking about was discussed before. READ!! Not just a quick browse of the first page of each section, browse tru a few pages and read titles, use the search function, there's even a "google search" available! Just look at the top of the page and you'll see these search functions.
Never heard of "swim or sink"? Soon, peoples here will let you sink because it seems you don't want to swim.
