I feel like a lot of the countries that are already there need improvement. Maybe it's just me, but although WS is my favorite part of WDW, it seems like they could just do so much more with it.
For instance, they could build more rides. I know they do not have a lot of space, but I'd rather have a ride than a bunch of stores filled with really expensive things.
There is so much more they could do with Italy. For instance, they could add something with Roman mythology, or ancient Rome. They could have a museum with replicas of ancient Roman monuments.
I'm not that familiar with German history, but surely they could add more than just stores. Germany & Italy, IMO are the two pavillions I spend the least amount of time in. Although Biergarten is my favorite WS restaraunt.
The Mexican ride needs to be updated, or at least it did last time I was there , last July. The videos of people shown in it look like they were filmed in 1973. I know the Emporers New Groove was not set in Mexico, per se, but maybe they could incorporate that , somehow and do a ride.
China and Japan could use rides. China, at least, has a movie. Japan needs something. There is so much history there, that surely they could pick a time period and do a ride.
Morocco, they could easily do an Aladdin ride, or show. Or not even an Aladdin themed ride. Just a generic magic carpet ride, maybe with the same technology used for Star *****, flying over Morocco, showing riders the beutiful landscapes.
Canada could surely add a Brother Bear ride. Maybe a ride through the wilderness.
I don't mean to sound negative, as I'm sure I'm in the minority here- but I for one, can not afford the items in most of the WS shops. I love looking at them as much as anyone, but I'd much rather have museums, history, and rides than an overpriced mall.
And despite this - WS remains my favorite part of WDW. I love the feeling of being transported to exotic places, I will likely never visit IRL. I just wish they would do more to spruce it up.
