CDF has a prix fixe menu with 3 courses if you dine before 6.
do not worry about needing 3 courses, 1 will surfice!
as to your earlier question, CRT and LeC are probably the only ones you ll struggle to get, just be flexible... i would also reccomend eating earlier than wayne said, (no offense wayne
) but his son is older than your kids, and very used to wdw, heat and excitment etc. on a first trip book meals for 5-5.30. why? allow 90-120 for dinner, you ll be out in time to wander before fireworks, or get back to the room if kids are tired. obviously if you having a lazy morning/late night then its different.
you ll also have more chance of eating if you avoid the "rush" buffets will be quieter etc.
also means you can brunch and have your snack either "before bed" or for bfast in the room. always try and avoid eating at "normal" times, esp CS, as they will block you for longer than you think....
as for planning, we have looked at where the emh is, and avoided like the plague! as we are there at the saem time, if you pm me, ill email you the sheet i have done, as to what parks what days, it might help... but remember its only MY attempt, and is not necc. the best options for your family!
