What day of the week is the least busy?

Thursday

We went on a Saturday it wasn't too crazy crowded! We thoroughly enjoyed our day there. The grounds are beautiful and the museums are very interesting! All I can say is take your time and enjoy yourself.

Monday and Tuesday are less busy.

On warmer days try going around 11. Cooler days are always going to be busier

Not sure, we went last friday and wasn't bad at all.
