OT - DC Field Trip

This is off topic, but I felt there are a lot of knowledgeable people here that could offer suggestions.

I am chaperoning my son's 8th grade field trip to DC. I wonder if any one can offer any tips on what to look out for at the following sites we are seeing. I know the basics, but thought maybe there are specific things I should keep an eye out for.

1. Marine Corp Museum

2. Arlington Cemetery - School is actually presenting wreath at the Tomb of the Unknown Soldier

3. Holocaust Museum

4. Pentagon

5. International Spy Museum

Thanks.

Kevin

PM me off line. I used to be a tour guide there a long, long time ago.
