The AP recently reported on teachers vacationing at the Supreme Court this summer:

WASHINGTON — Adele Dalesandro stepped inside the U.S. Supreme Court wide-eyed. She spoke in whispers, trying to absorb everything about the room she had read so much about but had never seen.
Her first impression was that it was much smaller than she expected.
“This is not something you can replicate in the classroom,” said Dalesandro, who has taught high school government and politics classes in St. Charles, Ill., for 14 years.
The teacher had become a student again.
Dalesandro was part of a group of 30 social studies teachers from around the country who got a behind-the scenes look this week at the Supreme Court as part of the Supreme Court Summer Institute for Teachers. The six-day program that ended Tuesday covered subjects ranging from choosing the court’s docket to nominating a justice, an especially relevant topic this summer with the upcoming confirmation hearings for Supreme Court nominee Elena Kagan.
