Best value Disney tickets for Florida

[triplets]

Just thought we had better start shopping round, we are going to Orlando for 17 nights in OCT. Will do some days at Magic Kingdom, Animal Kingdom, 1 at Seaworld, one water park, and universal Studios I think this time, poss Epcot, whats are best options?

we bought sea world and universal tickets whilst over there, with sea world we got a 2nd day free. we got the hopper passess which let you go two water parks from the co op travel agents. dont think there is much difference wherever you buy them
