Taste of Florida?

Is it possible to get a good look at Florida in two weeks? I'd like to take
my wife there in January or February and just see what there is to see. She
has an aunt who lives just north of Orlando so we'd probably spend a day or
so there but other than that I'd like to have suggestions on where to go and
what to see.

We're an older couple without kids so things like Disney World doesn't sound
appealing but neither does a night-club scene. We've been to Hawaii and we
love beaches and nature but don't want to spend the whole time lounging on a
beach. I've been to Florida a couple of times but it was many, many years
ago so I don't remember much. Busch Gardens,Tampa stands out in my mind but
if I remember correctly the only ride there at that time was a tram/monorail
over an area that they called an African veldt. That would maybe be
appealing but I guess that's all turned into a big amusement park now so
it's probably not the same. Thrill rides don't thrill us!

I'm thinking that Florida's really too big to see much in just two weeks.
If so, maybe just from Orlando area down towards the Keys might be our
target area.

Any suggestions would be appreciated. TIA!
