In a typical year, the least expensive time to visit Walt Disney World would be during the winter off-season in January and February. This generally covers these two months with the exception of early January, when schools are still on Christmas break and the weeks around MLK Day and Presidents’ Day.
The simple reason for this is that there’s a lot more depth to it than that. The rule of thumb is that January and February are the cheapest months of the year, on average. There’s a little more nuance to it than that, given that fall has had better discounts (historically) and other factors might move the needle on a case-by-case basis. Nonetheless, we may assert with some reserve that 2023 will be the most affordable years of our lives, with an asterisk next to it to account for potential price reductions in Fall 2023 (those discounts will not be offered this year).
