Hi Marla,
I hope you were able to make those ADRs that you were looking for. I know how important it is to try and get your restaurants and dining times so I can see why you were focused on that task. No worries, we can steer you in the right direction for the scavenger hunt you are looking for.
The Family Magic Tour takes place at Magic Kingdom and is open to all children and adults. The "tour" lasts around two hours and is an interactive experience thru a number of Magic Kingdom's lands in search of clues to solve a puzzle or mystery, very similar to a treasure hunt. At the end of your hunt, you are rewarded with a visit from a Disney character. The adventure usually starts around 10am and is offered once a day. We paid around $27 per person for our tour. It is a great time for all and something even the youngest in your party can enjoy. My boys loved to track clues throughout Magic Kingdom and see where the clues led us next.
You can find additional information about this and all of the other amazing Disney World tours by going
here. Many of these tours are very popular so I suggest making reservations. The reservations can be made ninety days in advance by calling 407-WDW-TOUR or 407-939-8687. The reservationist will be able to help you with current availability and prices. Be sure to ask about any discounts offered to annual pass holders or Disney Chase Visa cardholders.
Hope your family has an amazing time saving Magic Kingdom!
