Are you a AAA member?
Also, depending on your money and what family members you're bringing, Busch Gardens is a MUCH better deal than any of the Orlando parks. A lot cheaper ($84/year for a FL resident pass*), much less crowded (I've never stood in line for anything more than 15 minutes), and kids love the animals. It also helps that a lot of the shows and specials are more interesting for adults too, and not just little kids.
*By comparison, a Disney annual pass, for a FL resident, is a $99 down payment AND $19 (IIRC) per month for the whole year on top of that. It's completely asinine what that park costs.
