I would look at precooking a few meals to help max time out of camper at the fort. Such as taco meat, cook and freeze before hand. Gravy for biscuits.... Also fried chicken and pizza to go from trails end is great options.
Make sure AC is working. On our hybrid I used reflective material on the tent parts and the windows makes a world of difference. PM and I will provide details.
Offsite, take the kids to gator land. bring your own hotdogs. Really. This place rocks, as you walk over gator swampland and toss out hotdogs and they eat them.. There is a cat walk in the back swamp and a tower.. I took my boy early one day and it was just the two of us.. Dude it was Awesome.
Other boy stuff.
Lego store at downtown disney.
Fishing at the lake.
Walmart dozen worms and 6 pack for dad!
Costco for steaks ,the sites have grills, will need charcoal
bring your own smores for chip n dale.
water parks are good. but cost.
Mini Golf, there is also par 3 course. Maybe check out kissmee area for other items.
Dad could you do just 1 star wars day at Hollywood studio? would look at extra magic hours. Also if you do it, and plan on doing jedi training, be there at rope drop and find out where signup is at. it fills up fast.
Heck, maybe you take a COCO beach/NASA day.
