The rooms are pre-decorated, but you may bring other decorations, if desired, such as table decorations, banners, etc. Farm Country does have room for a pinata.
Any type of balloons are NOT allowed at Farm Country due to the safety/comfort of the animals.
Helium balloons are NOT allowed at the Museum of Ancient Life, the Museum of Natural Curiosity or the Butterfly Biosphere due to the issues of balloons floating to the ceiling/landing on exhibits.
