I've never stayed at the BW in concierge, only the GF, Poly and the AKL. My favorite for overall experience is probably the Poly with the AKL a close second. My main problem with the GF concierge is that EVERY CM I encountered seemed to give me attitude. It seemed that way to me to every guest staying there unless you were a celebrity. Yes, there were celebrities there, and they were treated with the utmost respect and fawned over. Now, I do not expect or neither want that kind of attention, but common curtosey should be given to every guest. Every time I even tried to ask the concierge desk ANYTHING, it seemed like such a HUGE task for them. Even making a PS!!! I just got so annoyed with them, I made my own PS's from my room!!! I also had to wait until almost 5:00 for my room, and the list could go on and on..... I think if you're at the GF when normal people are there, not dripping with money or a celebrity, the concierge is fine. But if they have to "deal" with someone, you're better off somewhere else.
