There are docents that run tours often for students. I don't know how to schedule but if you walk in the main entrance, you can ask at the desk. Saw a tour this past week.
Yes
We were there about a year ago and we had a guide.
No, there is no tour nor tour guide. It's a do-it-yourself tour. Nothing like it was 20-30 yrs ago. Big disappointment when I took my granddaughter to see our Capitol bldg.
