I have to wonder if they look at requests. But just because you didn't get it, doesn't mean they did or did not. If what you REALLY wanted was ground floor, that should be what you should have said. Probably would have been easier and my bet is the ore flexible you are, the more likely you'll be to get your request.
Side note:
not directed at the OP, just general request observation
I rarely make any requests anymore. A: we rarely got them anyway (even though we go in "slow" times) and B: we've been pleasantly surprised w/ what we've been given often. I wouldn't doubt that room assigners just get tired of requests and specifically the ones where people have it down to a room number. I don't know how it works but I wouldn't be surprised if in day after day of doing that job, a few might get...oh, lazy.
In the future, if I were to make any requests, I'd pick the aspects of a room that ere MOST important to me (i.e. ground floor or 3rd floor, near the pool, etc.) and leave it at that. That's going to be MY M.O. anyway.
Good luck to the micro-managers!

Haven't ever stayed at a value, have no desire to. Every time you step a little higher on the resort "ladder" you'll find it hard to go back!
Most do anyway. Disney knows this! Evil Disney! They upgraded us to a lodge concierge room at the GF once and we've been spoiled and ruined ever since. See the DVC pic below?
BEWARE of Disney pixie dust! it's EVIL!
