Yes. Brown's Seaplane Base in Winter Haven, FL (about a 40 minute drive SW of Orlando). Flew the J3 (Cub).
To answer your last question simply: yes. To go into more detail: it was the most fun weekend I think I've had in my entire life! I was in MCO for a convention, and had a chance to stay at a timeshare through the weekend at no cost, so jumped on the opportunity to stay and do my SES.
At the time, the ink was barely dry on my PP-ASEL. I asked my CFI what he thought about me doing it with so few hours, and his only words were: "Go for it! Why wouldn't you?"
It took two days, the first we did about 1.5/2 hrs of ground school then flew, then lunch break, then flew again. I went home and studied (each flight was about 2hrs) then came back the next morning and flew, then went RIGHT into my checkride. In total I got right around 6-7hrs of SES time.
Flying the Cub was a blast - flying one on floats was even more so (picture buzzing along a shoreline looking for gators with the door down, or bobbing quietly in the middle of a lake with a warm breeze while your CFI goes over taxi procedures with you, and you've got your own little slice of heaven).
I can honestly say it helped my 'stick and rudder' skills immensely - so much of flying that plane and flying floats is simply feel.

I recommend them HIGHLY - and in particular, my CFI was great. I will definitely be back for more seaplane flying in the future.
