We there mid-February. As much as I like to think WDW is the happiest place on earth, unfortunately there are rude people everywhere, including Disney. I did notice one thing with the CMs. 99.9% of them where wonderful, but the ones that were less than friendly, were downright crabby. It was like there was no in between. Either they were over the top "Disney" happy, or mad at the world. Again, a very, very small number that didn't display that the kind of Disney magic we've come to know and love.
Now, about these so called foreigners. One late night while waiting for a bus, we thought we were going to witness something. We were the second family in line waiting for a bus. Since I don't want to offend any nationality, lets just say there was a family of "vampires" behind us. (We don't have any vampires here, do we?) Now, there was a long line of people waiting for the bus. All of a sudden, as the bus approached, another family of vampires approaches the front of the line and are trying to weasel their way in. Okay, I could be wrong, but I got the distinct impression they knew they were at the front of the line and were trying to pull a fast one. All of a sudden Dad Vampire in back of us starts telling this other family of vampires that the back of the line is "back there". A few words were exchanged, nothing bad, but it was kind of amusing to witness these two families of vampires starting to go at it a little bit. The second vampire family did eventually go to the back of the line.
I agree with a previous poster, had these been two American families, it wouldn't have been noticed, but since they were vampires, they stood out in the crowd.
