Standard tickets for Disneyland Resort parks are sold in increments of one, two, three, four or five days of admission for a single visitor. Multi Day Tickets expire thirteen days after their first use, but visits do not need to be on consecutive days. Multi Day Tickets are not subject to the tiered pricing of One Day Tickets. The price per day for base admission and for the Park Hopper add-on decreases as the number of days increases. The cost for the Lighting Lane Multi Pass is fixed at a per-day price, and there is no discount for multiple days.
