An attraction would be great! It would be a big positive... hopefully. The two current rides kind of detract from their pavilions. A good quality attraction would be great!
Nevertheless I'm not saying having a great attraction wouldn't be a boon. I'm just saying an attraction doesn't make or break a pavilion. A pavilion can still be worthwhile without it. Norway used to have a large shop with local goods and flair, a ride representative of the country's culture, a buffet, an exhibit, and a bakery. Now, the ride represents an IP which has overtaken more and more of the gift shop and the buffet has become a way to meet princesses. It could be better if the inspiration of the land on the movie were focused on, but it's not really addressed at all. If Brazil has a ride that does the same, it could be better if it didn't have one. But I suppose it depends on if you care about the World Showcase... well... showcasing the world, or if you just want things to do, people to move through, and more money in the company's pocket.
I got off track there, but it's more talk about the entire conversation that's been happening. Nevertheless, I think I outlined ways that a pavilion can be interesting and really *be* an attraction without having a ride. It's not like a ride is the only thing that makes a pavilion worthwhile.
