brian,
Flagler does seaplane training, much closer but I have never trained with them. I graduated from ERAU in 2003 and did my float training closer to home in Maine. Twitchell's is a little far for you but rents floatplanes after your rating. Where you get your seaplane training depends on what you want to do with it.
During my first year of college, I thought that I wanted to fly for the airlines

Then I found float flying and I was hooked. I also got my helicopter license at Tomlinson aviation in Ormond Beach. Now I fly floats for a living in Alaska and and starting a 135 in Maine (wife doesn't like me gone from home)!
Wherever you do your training, have fun with it. However you never know where the rating will take you. It might even pull you away from that dark side
