If you haven’t been yet, it is amazing.
I have had very good luck following this list. Also read the comments for some additional suggestions.

A few other thoughts:
- I have heard from locals and my own experience is that, for whatever reason, weather tends to be a bit better in early February. Late January is really hit or miss. Early February is mostly “hit.” Of course, there is no predicting the weather.
- If you can, get a "Sun Pass" for your car or carry a lot of quarters/dollar bills with you. Tolls are everywhere in central Florida. The Sun Pass will let you drive around and pay via credit card.
- I do not mean to state the obvious if you already know, but check distances. Florida is a big state. For example, I totally agree about the JN Darling NWR, but Sanibel is its own worthy destination. It is 4-5 hrs from Orlando, depending on traffic.
- If you do go to Sanibel, great food, great beaches, amazing shells, and I'd see if you can find a deal on the "South Sea Plantations." Often expensive, but I've found good deals there before.
As for birding around Orlando, the list hasn't let me down yet, but I would say my favorites are Gatorland, Black Point drive on Merritt Island NWR, Orlando Wetlands Park, and Circle B-Bar Reserve.
Enjoy!
