I don't make a lot of requests, but there are certain things we know we'd like to have so we ask for those. It isn't a matter of the "Disney experience" not being enough, the room and view are part of that experience. Of course we understand that they are only requests and I've never complained about our room assignment. Then again, I've never been disappointed with what we were given either.
For instance, on our last trip, these were my requests at WL:
1)Non-smoking
2) Room on as high a floor as possible with a view overlooking the lobby.
We also wanted a view of the main pool and courtyard, but I knew with a lobby view that's what I would automatically get, so no need to add that to the list. We got everything we asked for. If we hadn't, I wouldn't have complained unless we had been put in a smoking room. That has never happened.
This year we're staying at CSR one night and I requested to be close to the main pool area, non-smoking. We're staying at OKW for the rest of our trip and I requested non-smoking, close to the main pool and hospitality house on as high a floor as possible. If we get these requests, great. If not, we'll survive somehow.
Whenever we go anywhere that I'm familiar with, there are usually views or areas of the hotel I'd like to have if possible. It's no different at WDW. I don't see any reason not to request the things that will enhance our vacation.
