When Disneyland first opened its gates on July 17, 1955, the pricing structure was dramatically different from today:
Visitors purchased a general admission ticket and then bought separate ride coupons (A through E tickets) for each attraction. The "E‑ticket" rides were the most elaborate and coveted.
Adjusted for inflation, that $1 admission would be roughly $11 today—a far cry from current single‑day prices exceeding $100.
