Hmm I see your point about the 1st day, you're right we should head to HS then leave chilling by the pool until last. changes planner
We're not doing Universal as we did that last year along with BG, sea world, Aquatica and Lego land. I didn't want to do both the Universal Parks and Disney, if they did The Walking the Dead theme all year then DH and the older DC's would've.
I love love love the petting farm, its like a family tradition now that we go. There's no where we I stay that lets you chase
chickens, milk the cows etc lol
Orlando Eye was only meant to be just that. ...20 mins then off to do something else but the 3 of the attractions where on offer so I got sucked into buying the 3 attractions for the price of two 
We won't spend long at the water parks so thought to split they days with Epcot.....I'll do more research on show times etc and might change that too. The last time we did the Disney parks was 2008 so its a bit vague.
Thanks for the advice, I'll look at your plan tomorrow and may copy a few of your days
