I've only made room requests for 3 of my trips, and I am 0 for 3 on getting my request met. Granted, I could have had my request met for a ground floor room at POFQ, but I would have had to wait a while, so I took the 2nd floor room they had ready.
For my stay at the Poly I requested 3rd floor Raratonga and was placed in Tokelau first floor. At POR I just wanted a room in the Alligator Bayou section, and was placed in the Mansions. Grrrr!
I should add that I paid for a prefered room at ASMu, and got put in the Broadway section. Which is definately NOT prefered. So even when I pay for a certain location, I don't always get it.
I don't know what gives. I'm very nice to the CMs. I make general requests, not requests like 3rd floor Raratonga with a view of the 2nd tree on the left. But I am denied time and time again. Those of you who get your requests, please share your secrets with me!
