The food will not be too much if you just snack for lunch. Just wondering what your MK expectations were for that day....Your CRT ressie is early, so you will get out in time to have shorter lines at the park. You will probably get a lot of Fantasyland done quickly with your DD after breakfast. You may wish to leave the park in the afternoon, once it gets crowded, and take a resort break. Are you staying on site? You could watch the parade, go back to the room for some AC, then come back for dinner and a few rides, then see the fireworks! Not a bad plan. We try not to plan two large meals in one day, due to the time it takes and the amount of food, but if it happens that way, we go with the flow. The characters are very different at CP and CRT, so your DD will probably enjoy both. Do you have a PS at CM? They have a great atmosphere for a birthday meal as well! For our DDs 1st b'day, we had PS at CRT, CP, Cindy's dinner, CM, and PSB. She loved them all, and they all treated her special for her birthday.
