I don't know what your financial or vacation time resources are, but I might take the kids and then plan another family trip somewhere else with DH.
As far as things that might be good to plan:
Pool time?
Bowling at that place at Disney Springs
Movies at Disney Springs
Amphicars at Disney Springs (those are expensive though)
Eating
My DH loved the fishing excursion (so much so that he booked another one the next day)
Mini Golf?
You told us what he likes...what does he hate? heat, crowds, lines, etc. Try to plan around those things as much as possible
Or like others said plan a central Florida or even a Southern California trip and just do the parks a day or two.
