Been planning our trip for 2015 and trawling web for best ticket prices and found this to be cheapest option.
Orlando Attractions is ABTA office in Ascot
By booking this way
Universal worldwide 2 days plus 1 day free (only 1 park a day) £87 (or £119 option for 14 days)
SeaWorld/Aquatica/Bush gardens 14 days £80
Disney Worldwide 4 days plus 4 days water parks/golf over 14 days £208.95.(£26 a person can be saved if you don't have fun days)
No wet and wild but total cost is £376.95 this will get you free gifts also
I just set up a order based on 2 adults + 2 kids total £1457.56 based on 2015 tickets

Prices also in $ but with current exchange rate cheaper for UK residents.
Hope this helps saving on ticket prices. As Combi tickets are £468 covering the same parks.
