Same here. I given up on requests period.

I never had one granted when I first checked-in. I think I am zero for five now over the years. Though I did get one request granted by begging and pleading at check-in and they changed my room assignment. I can never understand here on the DIS when everyone always seems to get their requests.

It is obvious to me that no human ever read any of my requests the times I made them (and these were not outrageous requests either). There are thousands of check-ins a day - no human is sitting there trying to match every requests - a lot of it is automated and the computer just picks the room at random.
The only possible reason I can think of for why my requests are ignored over and over is that I am at the end of the alphabet! Maybe the CMs who assign the rooms (if they even do that for people with no special needs) start at letter A and never reach the end!

Oh well - maybe the OP will be one of those lucky ones! I sure never was!
