Yes, Luke...but then they'd have to kill you...
JUST JOKING!
I have to say that visiting the Utilidors underneath Disney's second-story Main Street last November has to be in my TOP 5 Disney experiences of all-time and scratched a major "to-do" off my bucket list...I could have listened to the stories of the ingenuity and logistics of the passageways for hours, from trash removal to costume repair.
However, the famous Utilidors are not for general admission but can be accessed when you purchase either the
Keys to the Kingdom Tour or the more in-depth
Backstage Magic tour. The cost of the 4-hour-ish Keys to the Kingdom walking tour is around $70 per person and you must provide theme park admission. The 7-hour-or-longer backstage tour not only includes sites around the Magic Kingdom but all the parks and costs about $224 plus tax but doesn't require theme park admission. Best of all: it does includes lunch. You must be at least 16-years-old to do either tour, and you can call 407-939-8687 for reservations.
So, if you don't want to become a cast member or get arrested for trespassing, the tour is my recommended way to see the Utilidors!
