When we changed our reservation in early June, we received our reservation change almost immediately. When we up-graded our reservation a week or two later to WL, we never received a confirmation. Last week, we finally bought our air tickets; so dh called to book DME and our 1st night at Pop. He told the CM that we'd never received confirmation for our WL. CM checked all the information about our reservation on the computer, and everything was correct. A couple of days later, we received confirmations for both WL and Pop. Based upon what I've read on the boards, Disney had some problems with confirmation letters for about a week around the time we upgraded to WL. I think this is a fairly common occurence, too. It doesn't hurt to cal and ask if you haven't received your confirmation. I always feel more comfortable with the paper in hand...even if I have the confirmation numbers separately. I've never had a problem with a WDW reservation, but I have at plenty of other places.
