Hi,
EASA used to be another school up to last year. Which means another management etc., old threads are therefore out of context.
As for the period of the year you want to go: I went in Feb/March at another school in Florida, close to Ormond, and weather was a problem (mostly too strong winds). Therefore yes, take at least another week extra. But above all have your TSA cleared beforehand, I lost a lot of time just because of snow (not in Florida but in Virginia where everything is processed).
