I used to ride everywhere around greater Orlando (Orlando proper and several surrounding towns. It used to be a fairly exciting place to ride a bike. In the couple years before I left that area they added a Lot of bike lanes and made a big effort to get motorists to wake up (I guess winning the Most Dangerous Cycling City in the Nation award didn't go well with DisneyWorld.) No idea how it is now, but I can only imagine it is the same or better. i don't see why you would have any trouble.
Most of the surrounding areas are great for riding--bike lanes down some high-speed county highways where you would not expect them (highway 60, highway 17, etc.) You ought to have an awesome few days. Too bad the weather is perfect, eh?
Are you coming from the north or the south (if that would not be prying)?
