I understand completely. Sometimes we arrived at the Fort late afternoon and by the time we set up the popup and unloaded, the choices were delivered pizza, TE takeout, or a run to the grocery store (already hungry and tired).
Here are the pix of where you can get your TE takeout.
You can see the fireworks over the MK and the EWP from the Fort beach. The fireworks music is piped in too. A few of the low fireworks end up behind the trees on Discovery Island but they aren't many.
Dependind on your schedule you can get the GAG and eat it back at the cabin and then go to the fireworks/ewp but they also keep stiff paper plates and plastic KFS behind the cash register if you ask for them and you can eat at the picnic tables on the TE side porch looking at the playground and the beach behind it.
Do whatever's relaxing and get off on the right foot.
