In 1983, the ride was updated as part of an overall refurbishment of Fantasyland, as the Upside-Down and Oversized Rooms were eliminated and the Mad Hatter's unbirthday scene was moved to the very end of the ride. A new narration track by Kathryn Beaumont, the original voice of Alice, was recorded. To create more unified theming in Fantasyland, the Mad Tea Party attraction was relocated at the rear of Fantasyland to a spot adjacent to the Alice in Wonderland ride that same year. The Alice in Wonderland, however, did not reopen until 1984, one year after the rest of the new Fantasyland opened.
The ride was temporarily closed on July 15, 2010 after California's Department of Occupational Safety and Health pointed out that it lacked handrails on the second floor, exterior track portion of the ride. The ride re-opened with temporary safety rails on August 13, 2010. The permanent design was implemented in 2014.
On March 10, 2014, the ride closed for an extended refurbishment. In addition to regular maintenance, changes were made to the attraction's exterior. Walt Disney Imagineering also did some work on the ride's interior. The attraction officially reopened on July 4, 2014 with several enhancements; many scenes were updated with digitally projected images and effects (some of which include footage taken from the film, as well as some new animation), the Cheshire Cat figures received new special effects, and new figures of Alice were added to the Tulgey Wood and Mad Tea Party scenes. In addition, the second story exterior track path was widened and themed safety railings were added to the left (vehicle opening) side of the path.
Guests ride in caterpillar vehicles down the rabbit hole. Pieces of furniture, picture frames, and vases swirl around as guests "fall" down the tunnel. As guests enter through the Doorknob, they see the White Rabbit running off with Alice in pursuit. Guests then pass by Tweedle Dee and Tweedle Dum and encounter the White Rabbit, worrying about the time as usual. Then the guests go through the garden of flowers, who sing "All in the Golden Afternoon". Riders then pass the Caterpillar, who blows smoky letters and asks "Who are you?" and a Dandelion, who pops up, roaring, thinking that Alice and the riders are weeds. Next, guests enter the Tulgey Wood, where they and Alice meet the Cheshire Cat, as well as a pencil bird, an accordion owl, an eyeglasses bird, a horn-shaped duck with its ducklings, an umbrella bird, a cage bird, and a pair of hammer birds nailing a sign to a tree. They then go through the hedge maze and past some singing playing-cards who are painting a white rose tree red, splashing nearby bushes with paint. The White Rabbit announces the Queen of Hearts (and the king) and she plays croquet, using a flamingo as a club and a hedgehog as a ball. The King tells the riders: "Rule 42: The Queen always wins," and the hedgehog ends up rolling into a rose tree. The guests then enter the Queen's courtroom and the Queen orders their execution while a brigade of playing-cards leap towards the guests. Riders escape by pushing their way through the courtroom doors past two guards poised to attack. The vehicles then leave the ride building's second floor and descend in a winding path on a giant vine past the ride queue, before heading to the final scene at the Mad Tea Party. After the Mad Hatter and March Hare sing "A Very Merry UnBirthday", Alice proclaims that it's her unbirthday too. The White Rabbit ducks as a giant unbirthday cake with a dynamite candle explodes and the ride vehicles exit back to where they began.
