I would actually look at somewhere like Los Angeles if you like studio tours (where they actually make films and tv programmes), science (the California Science Center for instance to name but one) and exhibitions. There are also water parks like Knotts Soak City in Buena Park.
Personally I find it a bit boring - I have family there and access to a villa in Orlando, but really don't see the appeal.
The best bit in Disney were the street parades. It's very expensive and Disney is for younger children despite the obsessed adults Some of the rides are frankly shit.
Epcot is ok. Animal kingdom worth a look, but just a zoo.
The other parks, universal particularly, are very roller coaster heavy, which we loved for a day. Harry Potter is a draw too if you like that it's well done. The Kennedy space centre is excellent.
The rest of Florida can offer a bit. Everglades for a day trip, Miami for a look, Keys are pretty and a scenic drive.
However, it's a cultural desert. I really don't get it. I see it as a massive marketing scam and would rather spend my money going elsewhere. However that might be because I've been many times and sunshine holidays for the sake of sunshine isn't my idea of fun.
We once caught a cruise converted car ferry to Grand Bahama and drove a buggy round the island for a couple of days. That was good fun!
Check out the Facebook group Its Orlando Time, as lots of knowledgeable people on there. We hire a villa and tend to go to a park, or the mall or whatever we're going to be doing in the morning, then go home and jump in the pool! We have park tickets for every park this year, as we got an ace deal on them last year. DD and her cousins tend to do Disney and Universal quite a bit (they are all adults - supposedly ) and we will do a water park before it gets too busy. It suits us, as our family in the US come to stay with us, and that is the most important part for us. However, it depends what you want to do. There is plenty to see and do that are not the parks.
DD (17) and I hate big roller coasters and aren't into Disney characters, but DD loves the Disney parks. We enjoyed our holiday to Florida and stayed near Universal because she is a massive Harry Potter fan.
We also did an airboat ride and visited Kennedy Space Centre. We didn't do any water parks as they aren't our thing.
Definitely check out the dibb, it's a great website. I would say that perhaps it's not the place for you if you're not into rides or Disney, just because it is a lot of money! You don't want to pay all that and then be underwhelmed. (I'm desperate to go and the price scares me off!)
