LE Meridien Club Tower and Jules
If you want a no hassle, sure thing (most of the times) I think Jules is a pretty safe bet. I enjoy staying at this hotel when I'm in town for business not only for Jules but for the many F&be outlets on the property.
What I like about the club tower is that, its closer to Jules and the building is new with Jacuzzi baths in each room. If you meet a girl in Jules, or anywhere for that matter, and you wish for her to come to the hotel but you do not want to do the walk of shame, just leave before her and go to your room. Call down to the reception and inform the receptionist that you are expecting a guest and her name is xyz. (You need to get her real name though that matches with her passport that she must leave at reception) When you girl arrives, they call your room to confirm that you are waiting for someone and they send her straight up. You might have to meet her by the elevators on your floor as some floors have key access to the rooms through a mini lobby on your floor.
I use this method all the time and its the easy as pie.
Happy Hunting.
