The website is showing a price of $73.00/adult and $61.00/child for non-FL residents. The FL resident price is $54.99 for adult and child. I don't know where you saw the other price unless it was some kind of AAA discount or something of the sort.
it must have been for universal in hollywood, and i did not realize! i have been putting a lot of time into trying to find discounts with no luck1 I am still trying but not feeling hopefeul! $300 for one day does not seem worth it!!
