If you like animals SEA WORLD! Also think about Discovery Cove, right opposite Sea World. You may enjoy Busch Gardens and Animal Kingdom too.
Don't book tickets here tho!!!!!
Trust me and read on...
Most of the shopping malls and Hotel receptions run a time share visitation system where you can save HUNDREDS of $$'s on tickets for everything. You can do ones with different companies too! You get a free breakfast if you start at 7:15 ,a tour and chat for no more then 90 mins, get your tickets and go! I saved nearly $1000 in September
These 'tours' are tightly regulated in the US by FEDERAL law, so nothing like the Spanish horrors of years ago. Just say the maintenance charges are too high (which they are) and that will suffice.
Another scam if you are really thrifty is you will have to pay to park at all the attractions now (a rip off I know). If you get a Flex ticket you pay one parking for the day and go to any participating park for free, the same day! The tip here is that Wet n' Wild offers the cheapest parking and is only half a mile from Universal! So, drive into Wet n' wild, pay to park drive straight out again and down to universal, show them the ticket and get in without paying any more!
Beware of anyone charging you for advice on saving money on tickets, the only saving will be them banking the fee you paid them!!! Also, beware of 'special' numbers, don't believe that these are 'copyrighted', it's just a phone number! There are loads of these on e-bay too and the feedback will tell you everything you need to know...
Have a great time!
