I have family that swears that Discovery Cove is the best theme park in Orlando. I have not been, but it may be of interest to you. I love the Space Center. If you're looking for something more low-key and depending on your kid's ages, the Orlando Science Center is not. It's on the smaller side and can be done in 4 hours. It's a nice change of pace. For adults, shopping/ eating on Park Ave in Winter Park and take a canal boat ride from there is fun. The Morse Museum on Park Ave is top notch, too. It's centered around Tiffany's glass works.
