We are here now, so I thought I'd update.
This morning we entered DCA through GCH at 9:15. Got WOC FPs (9:00, blue), rode Soarin' (which was already open when we walked up at 9:20), got FPs for Soarin', and rode LM once before 9:55. You did not have to have a room key to ride LM between 9:30 and 10:00, but there was almost no line at all. My DH waited for rope drop (arriving 5 minutes beforehand), was the 4th person at TSMM, rode it and was back at LM by 10:15. (My kids and I rode LM twice more in those 20 minutes). When he walked out of TSMM (after being among the first on the ride), the line was already 45 minutes. After that we saw Disney Junior Live on Stage, rode Monsters, Inc., saw Muppetvision 3D, Turtle Talk with Crush, Animation Academy, and the rest of the animation building with zero wait times. It was great!
Yesterday we went to DLR around 8:30. It was not a MM. Peter Pan was already 30 minutes, so we skipped it. We walked onto Pirates. Then walked onto Haunted Mansion but my kids got scared in the waiting area so we left. Walked onto Jungle Cruise. Buzz Lightyear was around 15 minutes at 9:15. We did not go on Star Tours but the wait was 40 minutes at 9:15. By 9:30, when we came off Buzz, DLR was PACKED!
Moral of the story - go early.
