They provide tour guide services within this hour, and if you are in a hurry, they also provide self-guided tour brochures. We arrived at 10 o'clock, right at the beginning of the tour. They allowed us to participate instead of waiting another hour for the next trip. It was quite informative and we were taken to a very good part of the building. Some places are being renovated, and they were installing new carpets in the rooms of the "house" when we went. Our tour guide finished walking opposite the finance office. If you have time, be sure to stop there before leaving. If you are lucky, they will show you the safe and invite you to hold $500,000 in the safe. Parking notes: I parked my car on Congress Street West, where there are many parking spots. I think it’s 50 cents an hour, which is really cheap. The sights I saw are marked for a maximum of 2 hours, but that should be enough time to take a reason for traveling and walking. If you are lucky, you may be able to score points in a seemingly free place on W 4 Street.
