Any experience with Philadelphia International Music Festival?

Hi there. My D17 (violin) is attending PIMF and doing the Solo Performance Preparation track. She was able to win a scholarship in a local competition so we are trying it out this summer. Would love to know if any of your kiddos have experience there and how they liked it. She’s headed to NEC in the fall so she’s using this time to round out her rep and of course doing the concerto competition. She attended BUTI 2 summers ago and Heifetz International Music Institute last summer. We were attracted by FREE and SHORT this summer as she gets ready for school but she is a little worried it will not be as intense. Anyway, I would love any insight you great people might have. TIA!!
