Busch Gardens Africa has liberalized its kids-are-free admission policy to kids 5 and under, but there are rules and paperwork involved. To get the pass for the Tampa park that is good for the rest of 2010 requires registering preschoolers in advance online, printing out the filled-out form and bringing it to the park along with a copy of the child's birth certificate. Kids must be Florida residents. To register go to sesamestreetsafarioffun.com which also can be accessed from the park Web site, buschgardens.com. There are no sales at the gate without registration. Busch did not previously require registration or a birth certificate when only kids 3 and under were free.
