Our guide was Jennifer Barnes with Grand Canyon Adventures, everyone in my family LOVED her! She was so knowledgeable, prepared, fun, and respectful. Jen knows all the insider secrets! We had a big family (7) with 3 kids, 2 parents, and 2 grandparents. We had AMAZING tours, downtime when we wanted/needed it, saw the sites, wildlife, and great food ( : Jen kept us on track and looked out for us like we were her family. Thank you Jen from Rich and Irene. We highly recommend and when we come back we will ask for Jen again for sure : )
