Oh, I think I know what you mean!
When you book a package (hotel, park tickets, dining plan) you get a bunch of vouchers for different things, such as:
100 Play Points at a resort arcade
15% off regular price of Guided Bass Fishing
One free round of golf at Fantasia Gardens or Winter Summerland
etc
One of the vouchers is for "15% off the regular hourly rates at any Children Activity Center at Walt Disney World Resort. Minimum charge of two (2) hours per child. Services available for children ages 3-12". It goes on with some more fine print, but you get the idea. Its not a voucher for free care, rather, a discount coupon.
Hope this helps!
