I too was there for President's Week (2/13-2/20) and noticed the crowds were not bad. We had planned to be there 2/13-2/17, but our flight was cancelled since our DC airport was closed due to the blizzard, so the earliest flight we could get was the night of 2/20. But since we planned to leave the 17th, we had done everything we wanted to by noon that day when we found out our flight was cancelled (luckily we found this out in AK so we never left the parks for the airport). So this left the rest of the week to do lots of things we thought we wouldn't have time for until our Ocotber trip, including non-Park activities.
Waits on the weekend were bad, with the big rides having waits over an hour (all 3 mountains, Buzz, Pooh, RNRC, TOT, TT), but it was President's Weekend, Valentine's Day, and Speed Week with the Daytona 500, so all of those events at the same time brought very large crowds to the parks. But wait times definitely went down later in the week with those same rides having lines of about 20 minutes. In fact on one day, TOT had a 45 minute wait but the Fastpass time was only 15 minutes from when you got it! We had PSs for most meals so I can't say much about restaurant waits, but with most of our PSs we only waited about 10 minutes.
One comment about EE that really bothered us, however, was that at MK non-resort guests were allowed in for EE on every EE day. AK and MGM seemed to be checking, though not every guest, and we didn't go to Epcot on EE day so I don't know what they did. But we were at MK before 8 on both EE days we were there for and both times they let everyone in and did not ask to see a resort ID. This was especially bad on Sunday 2/16, since weekends are generally more crowded and with all of the extra people the wait times for the EE attractions were over half an hour by 8:10! We went to guest services to point out that we spend good money to stay at their resorts and could have stayed at a Motel 6 and still gotten the same priviledges. The CM told us maybe we didn't think they were checking for resort IDs but since many resort guests have their admission on their room keys that they didn't need to check. However, we have APs and so those are not on our room keys and we were not asked on either day to show proof of staying in a Disney resort. Normally, we would not care, but since the point is that resort guests can enjoy rides without the big wait times and that was not possible since htey let anybody in, we told them about it. Basically, they didn't do anything but said we could wait and speak to a turnstiles manager, which we didn't feel like waiting for so we left. It was pretty surprising though since it was very crowded on those days and during our NYE trip they checked resort IDs at every park.
