OK, I found these forums a week ago and have quickly become addicted to them. I've gone so overboard with my trip planning that I might be traveling alone by the time we go because I'll drive my wife batty! Either way, you guys are totally awesome, so I will continue to ask all of my questions in the hopes that you will continue to answer them. 
Our trip is June 6-12. We're planning to front-load the trip with the long, exhausting days in the hopes that we can sort of wind down towards the end with less-stressful activities so we won't be completely exhausted when we go home and, eventually, back to work.
It'll be me, my wife and our two boys (12 and 6). We're driving from Nashville and we'll roll into town on Thursday afternoon/early evening. We're going to be staying at a rental home, so I figure the first night will be mostly grocery shopping and getting situated to hit the parks hard for the next few days. We'll be at Hollywood Studios bright and early for Star Wars Weekend on Friday and we'll hit the other parks on Saturday and Sunday as desired...then we'll try to start slowing it down a little. On Monday we're planning a day at Sea World and currently don't have anything planned for Tuesday before leaving on Wednesday morning to come home. I'm trying to find some smaller, somewhat less of a rush-rush types of things that we can do. I've got a few ideas, but I'm hoping you all can give me some more.
I would really like to squeeze Gatorland into the trip as that's the place I always remembered from when I was a kid. Depending on what time we get into town and what time they close we might even hit them on Wednesday afternoon before we do anything else. The only other item on our to-do list is that my 6 year old has asked us for years if we would take him to the ocean so he could see it. From what I've found it seems that Cocoa Beach is the closest place to do that about an hour away, so that's probably where we'll go. So on Tuesday I figure we'll get up and drive to Cocoa Beach for a short time, but that will probably get us back around lunch time leaving a lot of the day to do other things. What else is there to do?
Kennedy Space Center seems like a good option but it's pricy (since we'll most certainly be broke from the previous 4 days!) and I'm not sure it's a good fit for the whole family. Are there any other local attractions you've found in the past that you would recommend for a 2-3 hour or half-day activity?
