Hey all, I just returned from a week's vacation at Disney World and although it was so much fun, these Brazilian tour groups made certain things miserable! They were loud, obnoxious, and beyond rude. They would push and shove their way to the front of theaters and lines. In one instance, they knocked my 1 year old niece over without so much as a backward glance. Not only did they cut lines, but they were constantly yelling, loudly singing, and clapping. It was a constant headache! They rarely had any adult supervision, and the only tour guides I encountered would stand at the fastpass machines with at least 100 tickets and eat up all the fastpasses for hours. Not only did I hear numerous guests complaining, but one CM at The Enchanted Tiki Room was telling my sister and I about how the tour group kids were in a fist fight at Epcot, jumped onto the track on Big Thunder Mountain, and were attempting to sneak past seat belt checks on certain rides. The other interesting thing the CM told us was that if you attempt to complain to an adult with the tour guide, most pretend that they don't speak English. But, apparently if you say that you are going to complain to Guest Relations, they suddenly speak perfect English. I can't believe that Disney allows this kind of behavior year after year. These tour groups were a total damper on my vacation, and i hope that they are regulated or separated into different weeks in the future. Has any one else experienced these Brazil tour groups?
