If you're a fan of live theater, book yourself some seats for a play at Golden Bough Playhouse. Look online for scheduling details.
This arts and culture attraction is free to visit, so you can have fun without spending a thing. However, Golden Bough Playhouse isn't the only place to visit in and around the beachside neighborhood of Golden Rectangle. With Monterey Bay Aquarium, Fishermans Wharf and Carmel Beach not too far away, you may be tempted to stay a while longer.
