You'll have to call the schools directly. Most places don't post their rotation sites because the preceptors they have can always change. Thus, a rotation that they did last year may not be available this year (e.g. preceptor goes on maternity leave, moves to a different store, etc.). You can only image what could change over the course of three years and how many times they'd have to update the sites on the website. Thus, if you want a better idea, you'll have to contact whoever coordinates the rotations at the schools you're looking at.
