Everglades are swamp... only tour / airboat if you really have nothing better to do and like feeling danger of getting eaten by gators or pythons if you fall off the boat... I get why they are a "part of the ecosystem of Florida and its watersheds etc." but its not... beautiful
The amusement park thing is its own thing, WDW and Universal are both great in their own respects - water parks are like "action parks" it really depends on what age you are targeting - younger kids the small water park at the back of Lego Land is awesome - Lego Land in general is great because it is all targeted to younger kids, it is the Bush Gardens and Adventure Island for kids not big enough for those two. A step up from Lego Land water park is WDW Typhoon Lagoon - I would skip Blizzard Beach, they have let that place rot and it looks bad... when it first opened it looked like real snow and was really well done, now its all just dirty poorly textured cement that looks like crap and any surface that is (was...) "snow" will tear the shit out of your skin. This is why I look forward to if they keep up Avatar land in Animal Kingdom, it looks awesome now - but if it is not kept up I can see the blending of fake + real fauna etc. will age badly.
The new Orlando water park is the shit for adults and older - Volcano Bay and also Wet&Wild A++ and I like them better for more "thrill" stuff - but for kids, as stated above - LegoLand and Typhoon Lagoon.
There are a lot of historical stuffs all around, spanish forts etc.
Miami is Miami, go to the titty beach etc. and of course if you are close to Key West, go
Florida is bigger than you think, if you start "central" in Orlando its 3 hours to the west cost, 4 north or 4 south to get to the ends of Florida - then another 5 etc. to cross and go to the panhandle, but panhandle Florida should be another state, those guys....

Florida does have a lot to offer, but none of it is really...in one spot. You will get "the most" by starting in Orlando and do the theme park stuff, hit up the Space Coast for NASA stuff, then go down to Miami and do...whatever it is that is Miami, si hablo - and then Key West it.
