These threads always crack me up! We've probably logged more WDW July park hours than all combined posters on this thread, as we've been going every July for 2 weeks straight for 10 years! At some point, we've been in Disney during every day in July!
We found the tour groups to be less this year, than in year's past. We did leave the parks on July 12th, but up to then, there weren't as many as in past years. They never bother us, nor do we get bothered by chanting or the like. We've walked in the middle of the tour groups with our stroller, and have not been bothered, we've had some of the teens return an autograph book that fell out of my daughter's hands just this past trip, etc. Honestly, people are so hot and bothered on here about the tour groups, that they go looking for problems. It's a self-fulfilling prophecy, IMHO. Will there be some rude behaviour? Sure, just like there is in all parts of the parks. The only thing that is common with the groups is the Fastpass ticket situation, and seeing mostly exhausted groups of teens sitting on the curb over 1 hour before fireworks in order to secure seats. Besides that, no problems for us in the thousands upon thousands of WDW park hours we've logged.
As I've commented on many times, we have witnessed more rude behaviour by Americans - both adults and teens alike. We were cut in line, banged into, and stepped on by rude American parents who were impatient this past trip. Not Brazilian teens...
Not really sure what the purpose of these threads are? If you don't like the tour groups, don't go in July. The fact is, they have just as much a right to be there as any of us.
Now, if you witnessed rude behaviour, or safety issues, then you speak to a CM. Just as if you witness an American breaking a rule or someone from another country - if anyone breaks a rule that is a safety concern, then speak to a CM.
Cutting in line, making noise and standing around are not exclusive to Brazilain teens, as we see lots of this by other groups of people as well.
