summer opera program

<p>Our D has been accepted to a few opera programs and we're at a loss as to which one would be best since she'll be applying/auditioning in the fall to colleges/conservatories.
Has anyone had experience with Interlochen's opera program, Walnut Hill's or Bel Canto Institute? She's already done a lot of choral work, so isn't tempted by that component.
Any feedback would be greatly appreciated! Thanks!</p>
