342 Donald and Darlene Shiley Stage Tips
Casual dress. I think it's warm because the seats are so close together.
Give yourself plenty of extra time to find parking, and expect to walk some distance to the theater.
Whisper House is 90 minutes without an intermission. Either drink/eat before or skip it.
Sometimes AC in theater can be blowing. Make sure to take jacket with collar.
It can be pleasant to leave room for walking around safe areas of park after picking up tickets.
