Aloft and Four Points are both great, no problem with guests at either and no joiner fees. Should you make arrangements with a girl, or girls, ahead of time and they're going to meet you at your room, hotel staff will call for your ok and escort your guests to the elevator. No direct access to the rooms, unfortunately. And they are both vigilant about getting your ok before they let the girls go. I am at the Aloft now, and frankly it doesn't seem too busy, but rooms are harder to come by at the Four Points so I think it's a bit more popular generally. Both get excellent reviews on Tripadvisor, for what it's worth. If you have SPG points both are level 2 properties (out of 6) so you are getting great value for those points, too.
