We've stayed at Embassy Suites several times and really liked it. They serve a complimentary breakfast in the morning. You can buy a ticket for the shuttle that will take you to Disney, they pick up and drop off right in front of the hotel.
Don't miss Space Mountain and Indiana Jones. Big Thunder Mountain has just recently been redone and I'd make that a priority too. You should also plan to see the Disney classics like The Haunted Mansion and Pirates of the Carribean.
The food in Disneyland is much better than it used to be, but be prepared to pay for it. If we are getting tired and thinking about leaving the park at dinner time we will wait to eat until we are out of the park.
Have Fun!!
