Note: Disney Merriest Nights was not offered in 2022 or 2023.

On 5 nights in November and December, Disneyland Park will host the Merriest Nights. This separately-ticketed event will feature different holiday-themed gatherings in different lands. On Main Street, U.S.A., Mickey is joined by Kermit the Frog and Miss Piggy while Tiana welcomes guests to New Orleans Square. Miguel from "Coco" hosts a party in Frontierland, Lilo & Stitch entertain in Adventureland, and Queen Elsa and Buzz Lightyear take care of Fantasyland and Tomorrowland respectively. In addition to the parties and characters, the celebration will feature photo backdrops and specialty food and beverages.

Select attractions will be open and capacity will be limited, so parties like this can be a good time to get in a ride on a normally busy attraction. There are only five parties scheduled in 2021, so demand is likely to be high. Prices start at $165 per person and a ticket allows the holder entrance into Disneyland beginning at 5 PM with the party itself running from 8 PM until midnight.
