Is it possible for your family to make a trip for a quick visit before you decide, even if it's only one parent and one child? I grew up in Florida, taught school there for 35 years and St Augustine is my favorite place! There's a lot of history, but many of the attractions are kid-enticing (took many school groups there over the years, so I know!). Another plus for your kids is you wouldn't be far from Jacksonville, which is a BIG city, so they'd have all the fun of living near beautiful beaches, but near a city for concert, etc.
