Updated 6/30: We continue to prioritize children's health. As a high-touch facility that serves primarily children under the age of 12 who are not eligible for vaccines, we continue to require face masks for all unvaccinated guests over the age of 5, and strongly encourage masks for guests ages 3 & 4. Disposable masks are availabe at the front desk .
