During our stay in June we had breakfast at the YC twice using room service. We wanted to take advantage of EE so we tried room service and it was really great. You can order the night before using the card in your room that you leave on your outside door, or just call the night before. The first day we used it the order came at 6:30 am and the second time it was 6:45 am. The food was really good and it gave us plenty of time to get to the EE at the parks. They will bring your food at the time you request.
I would recommend this for anyone trying to use EE from the Boardwalk area. Since most of the restaurants seem to open at 7:30 like Spoodles (our favorite for breakfast), using room service is nice and relaxing, and easy.
We easily manged to get to the parks early and beat the crowds.
