You;ve got some very interesting answers so far, I thought I would throw my opinion in here.
There are so many diverse areas of FL. I grew up in South FL and now live in Central FL. North FL is completely different and so is East from West and the Keys are different as well.
I can't believe people feel that they can generalize people in a certian area, that to me is very strange. I have not met every person in South FL North Fl, Central, etc so I can't really tell you what the people are like. In my opinion every person is differnt from each other and you will interact/react to them differently. I don't think you can choose a region to live based on the "type" of people. That would be like me thinking every person in NJ is like "The Situation"
Out of South and Central FL I LOVE living in central FL. We are a few minutes north of Orlando and it is an amazing place to raise kids!! We are about 40 minutes from Disney, about a half hour from the Cape and Coco Beach, there is a childrens art center, history center, and science center within a half hour from our house. There are parks everywhere, we have easy access to the highway, and festivals like you wouldn't believe! I LOVE that almost every weekend we can find a FREE event to go to. There are hometown harvests, TONS of farmers markets, last week Playground Magazine put on a huge event that was completely free and so much fun for the kids. We were there for hours and didn't even go through half of the event. We are also about 10-15 minutes from UCF, which is an amazing school and getting better every year. It's great for football games, basketball games, and there are always tons of kids shows at the arena. The shopping in Orlando is great as well. Tons of discounts and outlets for the tourists that locals can take advantage of.
I like that the weather changes here. We are ususally 5-10 degrees cooler than South FL so we have more of a "winter" and a slightly cooler summer. I'm not going to lie the summer is HOT, horribly hot. Every year we get so excited for November to finally get here! This winter was very cold for us. We spent weeks in the 20s and 30s. It is a different kind of cold here than up North, I think it feels cooler, and this is from spending many winters in ILL. But good news is we don't get snow, which means no snow suits, boots, hats, etc for the kids. But there were a few mornings that we had to start the car early and scrape ice off the windows.
Pretty much the only thing I like better about South FL than Central is that the beach is only 10 minutes away and that every house has a pool! In Central FL only about 1/2 of the houses have pools and that was so strange to me coming from South FL. But there are splash parks everywhere, and community pools all around. Chances are you will quickly meet people that have pools at their homes.
As for schools, not all public schools are terrible or even bad or good. There are some AMAZING schools around you just have to research. I live in Seminole County (and used to teach here as well). We are one of the best in the state. Also I was educated exclusively in public schools in FL and I feel that I have recieved an education that I can be proud of. I have quite a bit of family in other parts of the country and I know that I was better educated than others. Education is an area of life where input seriously effects the output. In any part of the country you are going to get more out of a child's education if you, as a parent, are willing to participate.
It's going to be impossible for anyone to make this decision for you. :) Good luck and you can let me know if you have any other specific questions that you think I may be able to help you with.
Sorry that I kind of went on for awhile, but some other responses kind of hit a nerve with me. Blame it on the post partum hormones. :)
