Hi Lisa, my daughter has been offered a place in this as well and we are having the same concerns.
We are more than likely going to give it a go and hope for the best.
I thought the audition was well organised and my daughter really liked the ballet teacher. It all seemed professional and genuine but like you I'm concerned about the lack of a website and information online. It's a lot of money to waste so it's good to read on here that people have had some positive experiences.
