I stayed there recently as well. Used points for a few night stay and got upgraded. I would agree that the rooms are a little dated. I prefer staying at the W and stayed there most of my time in Thailand. As far bringing girls back, I did for three nights straight and never even got stopped. The doormen would just open the door for me and that would be it. No ID at the front desk or any of that. There is a side door too (the one leading to the restaurant) that you can go in without going through the front. I also recommend it, I think it's the nicest hotel in walking distance.
