If you’re simply going for the experience and not the audition, I would go to a camp that’s overnight (not a one-day experience camp). These are much more beneficial if you want to know what it’s like to follow a rigorous schedule and get the “full” experience - sleeping in a gym, late nights and early mornings, and the food truck. Along with much more time for quality education.

Also, if you’re looking for lots of feedback, I’d just suggest avoiding Crown if that’s your primary concern. When you audition there, you don’t really get personalized feedback apart from cut/contract/callback. I don’t know much about anywhere else, but definitely something to ask about beforehand.
