we have done the CP 805a breakfast 3 times in the past year- no problems getting in, have had my ADR # but never needed it. There is a CM on the right side of the turnstiles letting people in--- dont worry, it is marked. These special entrances are on the left hand sides at Epcot and DHS..
also, we have been able to see all the characters and still get out for rope drop... asking for the check early as others have reccommend is key.
