If I had to choose just two groups then I'd probably pick Disney and Universal.

Disney has the most parks and is the primary reason why we visit Orlando. Universal's parks and ride and very good.

I would miss Seaworld though. We like that park. We've never visited Discovery Cove so don't know how good that is (and obviously have missed this out on previous trips).

Personally, I would try and do something like get a 2 or 3 day Base ticket for Universal and then a 1 day ticket for Seaworld. Doing that you might find the price comes to not much more than the price to get 14 day tickets to Universal.
