When is the best time during the week to visit. I read somewhere that some of the attractions are closed on certain days.

On weekends they make 4 or 5 of the buildings interactive and open to the inside as well. On weekdays you can only see these 4 or 5 buildings, visually from the outside. Weekdays less busy....

Ant time during the week lots to see Get ready to hike and walk a lot Have Fun

Weekdays are definitely better to avoid large crowds

Mornings are best, less heat more activities

We went on a Monday nothing was closed
