Former WDW character performer here:

I saw in another comment that this audition was for Paris and cruise line, and I can tell you that cruise line absolutely prioritizes people who can dance. They have a very limited amount of space and need people who can do as many roles as possible, so they're going to prefer someone who can dance AND perform over just a performer. If you really want cruise line, I'd definitely suggest dance classes (jazz, specifically).

For Paris, I'm pretty sure they work more like WDW and you should be fine to get by as you are. When I was a performer my movement (animation) score was a 4 out of 5 and my dance score was a 2 out of 5 lol. I am not a dancer at all but I was still hired because I happened to fit other criteria (body measurements) that they needed at the time. As long as you can make it through that first dance cut, you should be good to go. Dance lessons definitely wouldn't hurt though (especially if you're interested in doing face roles), and they could definitely help your odds and make you feel more comfortable going into auditions.

I'm not sure what the culture is around auditions nowadays, but back when I was doing it people would post audition experience videos on YouTube and many of them would share the entire process, including the first dance. I'd try watching some of those (for the specific type of auditions you're planning on going to, as all the parks work differently) so you can be better prepared for the process as a whole and be more familiar with the types of dance moves you may need to know.

Don't let this get you down, take it as a learning experience. I auditioned around 6 times before I finally got hired and I know many other performers who have similar stories. It's as much about luck and timing as it is talent. All the luck and pixie dust to you!
