While this may appear to be a negative it really is no harder than a UC application. If just requires your student to do a little more leg work. I also reccomend that your student give a resume or information to each so that they can write a really good letter. If they are apply for scholarships they will need letters for this as well.
I have had the pleasure to talk to a number of students that I done these trips in the past and all say that a college education at an Ivy League school is well worth it.
