From the parks FAQ page.
Smoking and vaping are only permitted in specific outdoor smoking locations throughout the park. Smoking Stations are designated in guest areas by smoking urns, benches and "designated Smoking Area" signs.
All indoor areas will remain smoke-free environments.
Please see our park maps for designated smoking area locations.
