I would suggest
Chef Mickey’s for your boys. While the Cape May Café is a cheerful breakfast (especially for the morning of your departure), it doesn’t quite have the same level of energy. I think your boys would enjoy the excitement of dining at Chef Mickey’s with the monorail passing by while they eat. Your boys will think
you are awesome for bringing them here!
If you have extra time after breakfast, take your boys for a ride on the monorail. You can stay on for a round-trip ride, or exit at the Polynesian or Grand Floridian to look at the resorts.
You may tour any resort that you visit (including the Beach Club where Cape May Café is located) and in fact, this is one of my favorite pastimes while in Walt Disney World. If you think you’ll need a more quiet morning, then the Cape May Café is the better choice. You can take the Friendship Launch boat ride (or walk) over to the Boardwalk resort after breakfast.
I hope you find some magic even on your last morning.
