Hi there...
Have a look at the Orlando Combi Ticket... I just bought a 5 Park Combi Ticket (Univerval Studios/Universal Islands of Adventure/Seaworld/ Aquatica/Busch Gardens) for £150 per adult at Orlando Ticket Deals.
This was far cheaper than a Flex Ticket - ok, so it doesnt include Wet n Wild, but we've been there before anyway and I think we'd much rather do Aquatica a couple of times.
The 5 Park Flex Ticket (which includes Busch Gardens and Wet n Wild) was far more expensive.
And this combi ticket is still valid for 14 days, and gives free shuttle transport to Busch Gardens.
Bargain!
