I did military style planning because my family wanted to go, and I was OK about it, but if I was going, I was going to do it once, and do it right. Not come home and feel like I'd stood in queues for most of the day, feel like I'd been ripped off, not seen enough and uncomfortable etc.
Florida is basically a swamp, the heat can be overwhelming which can drain your energy. I'd preplan for any holiday where I was going to be active with small kids in that environment rather than find myself in an unpleasant situation.
So VIP passes were booked where possible, private beach huts in the water parks, late evening tickets, I signed up for restaurant coupons, joined websites to take advantage of offers etc.
It's a very active holiday if you are trying to get multiple parks into one trip. You wouldn't plan a mountain hike without the correct equipment, clothing and food, I didn't see it any different to be honest.
We returned with the best memories of a luxurious stay, without any discomfort or feeling of being ripped off, and because I'd planned quiet relaxation days around our pool we were rested too.
