I would also love to see a Fantasyland expansion.
I would take a different approach though, and incorporate a Hercules attraction also behind the railroad. I like the way Adventureland is Paris incorporates lands within lands. So you have an Arabian area, pirates area, and hopefully in the future, a Indian Jones type area, all of which fall under the Adventure umbrella.
So Fantasyland currently is very much like the others, you could argue there is a land within a land regarding Alice. But I would like to go under the railway bridge and it turns from cutesy/village fantasy into ancient Greek fantasy, incorporating a large Hercules attraction and maybe even keeping the current boat ride underneath as something else.
Fantasy is stereotypicaly girly, but more boyish movies can also fit into a fantasy theme and Hercules is the best example. Visually and musically it would make a great attraction, its well known, its massively underrepresented in all resorts, and Hades is a bad a**.
O, and if you can't tell from my pic, I'm a big fan.
