So, let's talk about Canada. It does not encompass the large area that the hand drawn map would indicate. There's a lot of empty space to the north of it. In fact, a lot of Canada itself is empty space with a large "Canadian garden" as a rather... unexciting tribute to the country. And Canada is a weak pavilion, it is basically an upscale restaurant, a movie, a gift shop, and some outdoorsy scenery.
The buildings of Canada take up 1 acre.
The Garden of Canada take up .4 acres.
The forested area to the north has some booths is 1.1 - 1.3 acres.
So, by shedding some of the garden, there is a full acre and a half for development. Either a Canada ride or some other pavilion.
But since our insiders are telling us we probably won't get a new pavilion without an accompanying ride, and putting a pavilion and a ride in 1.5 acres is a bit too tight, then the options there would seem to be:
1. A Canada ride
2. An extension of Future World
3. Clear the space out for festival booths (which is already happening with the Tres Reis area)
