Again, I don't know the ins and outs of CET well, but based on my experiences at other properties, its not so much whether a host has autonomy to grant certain requests. Its all about the player. For example, my MGM host is one of the highest in the MGM Resorts hierarchy. But I still get bumped form Mansion every now and then even when he is the one that books me there. Conversely, the host I use at Bellagio is, by any definition, a junior level host but she has absolutely gone to bat for me on multiple occasions and fulfilled unique requests where I know she needed approval and/or had to have a discussion with her co-workers about which guests would get a limited in demand event comp. I am at a level where that stuff has to be approved regardless of who my host is. For big players, its automatic, no matter who there host is. Its why I try to develop relationships with hosts I like personally that I know will work hard to get me what I want. Then, I give those hosts more of my business.
I might be wrong, but I assume CP works in a similar fashion. And that means either my host there put forth no effort to get me what I asked for (for whatever reason) or I don't qualify at CET for what I was asking. Either way, I am more incentivized to play elsewhere at properties with hosts that I know will fulfill those requests
