We just came home. We were there Feb 25-Mar 4. The weather was fantastic, probably a little warmer than average but I went prepared with lots of clothes to layer if needed. The crowds were great. We went to MGM/Epcot on Mon 2/27 and most rides were walk ons with the exception of Soarin' and Test Track (we didn't check Mission Space). We went to MK on Wed and again, most rides were walk ons or we used fast passes. The longest we waited was on Dumbo-probably 20 minutes or so. Downtown Disney on Tues evening seemed a bit crowded and unusual for a week night. Maybe it was because of Mardi Gras.
HTH,
