Create a joint discount pass with three unrelated attractions

Partner with a museum, a brewery, and an outdoor outfitter, three businesses that do not compete with each other, to offer one combined pass that gives a small discount at all three when purchased together. Sell the pass through the visitor center and each partner's front desk.

Why it works: A joint pass encourages visitors to add a stop they might have skipped, and it gets three businesses actively selling the destination together.
