Hi Eric,
I used to stay there a few times between 1999 and 2001, was never hassled and really enjoyed the place. But last February, I stayed there 3 nights with my girlfriend (that I registered in my room) and every night, we were stopped by the security at the entrance of the tower wing, near the lift. They asked my room number and my gf's name, checked something on their computer and finally let us go. Not really the kind of behaviour we enjoyed. We were never treated like that in some other places (i.e. Sheraton Grande Sukhumvit, Belle Aire Princess, ...)
On the last night, as we stayed with a colleague of mine (Oli for the ones who remember him), I let my girlfriend walk in with him (of course, she carried the key). I followed them and it was really funny to see them stopped in front of the lift. I'm still laughing when I recall the guard's face when he realized that they had both their own room. :blah:
Cheers,
Bobby
