Here’s how it works: You rent a pair of headphones and an audio device (which looks like a cellular phone). Each room is numbered, so when you enter a room, you will enter the room number into the device and the audio narrator will give a brief description about the period and point out the significant pieces. If you are more inclined to learn than just look, my advice is to take the audio tour. Since it is self-guided, you control the pace, and the in-depth info that is provided will be vital to your enjoyment. And at $6 per person it is completely worth the extra cost.
