I’d like to know what the rehearsals are like for performers? Like parades, shows
etc.?
About halfway through my program, I was selected to be a Toy Soldier in the Christmas Parade. Before any rehearsals happened, there was an orientation session in which everyone in my unit was shown the parade route, the rehearsal space, and other stuff like that. Once rehearsals started, we would meet once a week for four hours. The first few sessions were just about learning the choreography and formations inside the parade building. From there we started training in partial costumes and marching around the building, and eventually we started doing full costume runs with music.
During the week before the show opened, the entire cast would do overnight rehearsals, as that was the only way we could practice the actual route without any guests seeing us. The first overnight was partial costume just to familiarize the performers and float drivers with the route, but then we had a few overnight runs with everything: Full costumes, music, floats, and some cast members lined up along the route to watch us.
The overnights were pretty brutal for one’s sleep cycles, but we all got through it okay. I remember my work schedule, which used military time, listed a rehearsal as ending at “29:00”. Only at Disney will you be expected to work 29-hour work days 
And you mentioned there was a scoring system based on your skills… Out of curiosity, what did you get?
I was a blue in movement and a yellow in animation, meaning that I was considered a stronger animator than a dancer. A very fair assessment, in my opinion. I’m not sure what that rating would correspond to in the current 1-5 system.
Also, I’m pigeon-toed when I walk (meaning feet turned slightly inward)… However , It’s not a disability that limits anything
I do like movements, dancing etc. Would Disney take this into consideration? As in would it affect my chances?
I’m honestly a bit mystified by the abundance of questions of the form “Hi, I am an example of some random corner case that no one ever thinks about. Will this help/hurt my chances?” If you rely on some perceived advantage and assume that it will get you in, you will probably perform poorly and not get selected. Conversely, if you assume that some perceived disadvantage is reason enough to not audition, then you won’t get in, period. I know it sounds corny, but just forget about all the special considerations and just give it all you’ve got. The worst case scenario is you have some fun and don’t get hired, end of story.
Did you meet any international Cast Members (in Entertainment) whilst you were at Disney? When they spoke to the guests (if they had to at all), did they have to speak with an American accent?
I did meet some international cast members in Entertainment. I specifically recall meeting a Pooh who was fresh-off-the-boat Chinese and barely spoke any English. As for face characters, I believe there may be some dialect training involved for those who are selected. I met an American performer who portrayed Alice (from Alice in Wonderland), a character that has a British accent. As far as I know, the first criterion for face characters is not their voice, it’s their face.
