The term chain in this case usually refers to the measuring instrument rather than a unit of length; the distances measured with such an instrument are normally measured in feet (and usually decimal fractions of a foot, not inches).

The tour will cost $99 (plus tax) for guests age 16 and older. A parent or guardian must sign a waiver for participants age 16-17. Annual Passholders and Disney Vacation Club Members will receive a 15% discount. For more information or to book, call (407) WDW-TOUR (939-8687).
