gavra_at_work -“It is inherently not Tzanuah to go “date watching”, which is what happens at these “lounges”. Go somewhere that you can concentrate on your own date.”
I personally have never done this, neither do I know anybody who has. Most hotels the lounges are quite dark and usually not that crowded where one is on top of another. While you can see other couples -almost never are you up close and personal to them. This term “date watching” is more appropiate for MO dating, eg. a pizza shop – brightly lit and e/o close together.
