Hello,
I returned yesterday from Disney World, and I know what you all mean. There where a lot of this tour groups but neither of them was bigger than 50 or 60 persons maybe they are so many groups and alike uniforms or clothing that you think they are together.
What I saw was that the group leader got the fast passes for the group while the group was on a ride, that way they where quickly on another ride.
But what I experienced also was that it didn't matter if the had fast passes or just did the regular line the wait time was the same. What I tried to do was just do the line on a ride without those groups or just do the line like everybody else.
I am from Puerto Rico and I know whose countries tour groups you are talking about, and I myself had some experiences. Talking a similar language I could understand what they speak and I know for sure most of them speak english and understand and/or speak spanish.
Most of them come from wealthy families, and go to the best schools that teaches them english, so they pretend they don't understand and/or speak it.
While doing the stand-by line for expedition everest there was a tour group and from nowwhere 5 more of them appeared and when the cast member ask them what they where doing they said "we are with the group", and she just let them in, and those 5 children followed to skip the line and after being the last ones from their group suddenly where the first ones of the group on the line. I was so mad, but I told to myself that I was there to have fun and I would not let anythig to disturb me but I said to my sister that if any other teen from the group that arrived after me sneaked in I would sneak in front of them. Affortunately they were the last ones.
The most awful thing happened to my family while waiting for spectromagic. We were already seated at 6:40 to get a good place at 8:00 it was already packed. Before the parade starts the is a cast member that play with the kids. At our side there where two kids and went top play while their parents where buying sodas and food, they put their bags on that spot so the people knew they were reserved, and the people could even thought the bags were ours. Suddenly from knowwhere 2 tour leaders seated on that spot whitout asking , seeing those spots were reserved and when the parents arrived and saw where very mad not for them but for the kids then up knowwhere 20 more kids from the group arrived and make themselve a space. I said loudly to my sister that if they tried to take me out or dare to stay in front of me but I will call the security( Disney Police) that was close and one of the group leader look at me and I knew she understand every word I said, because I knew they understood spanish. But very smart of our part we put our bags in the middle of each of us, and as soon as the parade started we put those children in front of the parade and boy, they were happy.
So I understand their attitude. But if they get fast passes it is fair that they used as any other visitor get's the right of this benefit. They are loud I know but I do like that happy spirit while visiting the parks or while going from a ride to another.
