Not given it much thought. But this is what I am starting with.
I am thinking like willy wonka's with a few modifications
Along with the river of chocolate there would be a "river of Budweiser" Complete with misting waterfall. And the freezing "river of Jagermiester" with a rope swing
The grass would taste like beef jerky.
Palm trees with coconuts full of Bacardi and OJ
Instead of lollipops growing, BBQ ribs wild throughout.
There would be animals, and they would all be the smoked version of themselves. Want smoke ham? grab a pig and take a bite. Smoke turkey? If you can catch it, its yours. Steak anyone??
The Ummpa Lummpa's would be hot strippers (they would only be stripping because they loved it, not because they had to.) I would have special glasses that made any male Ummpa Lummpa's look clothed because that would creep me out.
The burping room would remain the same. with an addition of a highly ventilated farting room off to the side (for when I'm in the mood)
The kids could play in a viewing area with one way reflective walls. They would have the best supervision so as not to worry. And sneaky secret things would be in place (remote control sprinklers, noise makers, smelly air nozzel blasters. slime cannon) So I can entertain my self by messing with them every now and again. (Nothing cuter than a confused kid).
The boat ride wouldnt change much other than you could cast out a line and do some deep see fishing. And I could drive.
There would be a cave of smells, Fresh bread, Cookies, ect. For spelunking.
Big tricked out golf carts for everyone to ride. With ramps, mud, maybe a speedway track. And cop carts that weren't fast or smart enough to catch us
Helium filled backpacks for us to sound silly whenever we wanted to.
Trap doors and secret passageways everywhere.
Massages area with all types of massages.
Warm mud or sand to walk on.
Those stimuli deprivation beds to nap in.
Warm Carmel swimming pool.
Mountain Dew and Pepsi rain forest.
