If you ever worked in WDW foods, you would hear that 50 times every time a group came to your location. It wasn't annoying or anything, it was just predictable.
In 1994, I drove a taxi in Orlando and WDW. Late one night I picked up a Brazilian tour guide who just had a booty call at one of the hotels. I asked him why there were so many Brazilian tour groups, and why they were always 15 years old. He said that a trip to Disney World is a rite of passage for Brazilians. It's like a Quinceañera for Latinas and a Bar/Bat Mitzvah for Jewish people. Those were his exact words. Back then it was just Brazilians, although nowadays it has obviously spread to other South American countries.
I stay away from the parks during the summer, but almost every time I go to Walmart there are busloads of them. It's most noticeable at the Poinciana Blvd and Turkey Lake Road locations. When I go to BestBuy it's usually full of South Americans as well, but not the tour groups. I don't think it's a big deal, and I'm not offended by their behavior, it's just odd to see so many of them. As long as they spend their money here it's a good thing.
