places to see around Orlando, FL

I will be in Orlando, Florida next week (2/11 - 2/16) for a
Java class. I was wondering if there is anything in the area
that I should try to see whilst I'm there. Obvious places of
interest would be aquatic plant farms, though tropical fish
farms might be of interest also. Mickey Mouse is NOT the kind
of pointer that I am looking for.
