Disneyland & DCA with 3 & 4 yr old-best recommendations?

[MinnieNMini]

We have 3 day park hopper passes and will be going to Disneyland/DCA on Monday-Wednesday. We will be there Monday afternoon and planned on doing Disneyland Monday/Tuesday and then do Wednesday at DCA with the Princess Breakfast at Ariel's Grotto. Is this the best route to go with Early Magic Hours? What would be the best rides to hit or best utilization of Fast Passes? COuld anyone share what they have done in the past that works for them? TIA!
