A Value Day in Disneyland ticket terms is a day where the ticket price is the lowest price offered. Disneyland's ticket prices are on a tiered date based pricing system. This means that the price of your ticket depends on the date of your visit. When Disneyland reopened after the Covid-19 shut down, their ticket system changed once again. Along with their prices! They removed the "value", "regular", and "peak" pricing terms. And it is now referred to in "Tier" levels.
