Seaplanes
If you want to go east rather then west, how about considering the Aero club de Como on Lake Como in Italy.
I had a very pleasant hour with an instructor in a Float equipped 172 (I-SAAB) several years ago and they also had a couple of Lake amphibians (Though IIRC one finished up at the bottom of Lake Como.)
Dunno the website but you could Google it.
