Merboy said:10, 11, 12 or so, fine. But when I hear "family-friendly" I think "this is something I can take my 4-year-old to see" but many of the elements of that maze were not something I'd show a 4yo.
I'd agree its not family-friendly - but its impossible or very close to it to design a maze that would work for kids younger than age 9. Honestly, when I look at Busch Gardens Parks, I don't see a park where you can bring a 7 and below year old kid and have them enjoy it. The main attractions at BGW are the roller coasters. The only exceptions to this are Cruse of DarKastle, Europe in the Air, and the Sesame Street Area.
