Hi Muchi,
I have to point out one thing about the February weather in Orlando: it is unpredictable! I'm very happy that the previous posters had good weather but you can't count on it.
February weather is not only unpredictable, but changeable. You could have days near 80 with cool mornings. But you could also have mornings near freezing with afternoons in the 40s. So you'll need to be prepared for both, since both could happen in the week you are there.
