We did a private VIP tour with Tony. We had two adults and two kids, ages 10 and 12. Tony provided interesting and useful information, and was accommodating for the kids (whether it was slowing down, pointing out sites they would be interested in, or stopping for unscheduled bathroom breaks). We felt that if we had done a regular group tour my 10-year old wouldn't have been able to keep up, or we wouldn't have heard all of the information provided as we likely would have been at the back of the group. We loved seeing all aspects of the park, including places that tourists typically don't go. It was fun and active (but not too much), and a nice change of pace from the bustle of the city. We would highly recommend this tour, especially for families with older kids and teens.
