We have done 1900 PF 3 times - the first 2 were awesome, but the 3rd time we were in a room off to the side and we didn't get as much character interaction.
'Ohana breakfast is our favorite breakfast! The kids love doing the little parade with the maracas, and the characters. We have eaten there many times and we have alway seen Lilo, Stitch, Mickey and Pluto. We also really enjoy the food there, especially the juice.
