I have. Its really kinda up in the air. I have a friend who lives in Orlando and she said January and February are the most unpredictable months. Basically it can be anywhere from 40s and 50s to 80s. Last time I was there in January it was COLD. 30s overnight and I think the highest it got was 60 one day. In the morning you will definitely feel it. There's no horrible daytime humidity, but it can feel damp in the morning and night. I would pack layers and options and even keep a backpack for in the park for changes during the day. I was comfortable in leggings, long sleeve t-shirts and a fleece last time, but everyone and their tolerance is different.
I have found AccuWeather montly predictions to be relatively accurate in the past where I live as far as temperatures are concerned. (I attached the monthly outlook below) Right now the days of my trip are saying mid to high 70s and lows in the 50s. I'm sure that could change at the drop of a hat and its still more than a month away, so I'll take it all with a grain of salt, but if it holds as we get closer then I'm planning on having some lighter clothes around... Maybe bring a sweatshirt or fleece for mornings and then change into a tee later in the day. Probably will stick with long pants, but I might bring a pair of capri pants if there's a really warm day.
