Date Opened: 2002
Capacity: The queue area can hold several hundred people but it is never that crowded.
# of Shows: Intermittent throughout the day
Photos and Autographs: Yes, and an official Disneyland photographer is on hand to take photos for later purchase.
Wait Times: Due to is prominent placement, lines for this meet-and-greet can get longer than usual for such things, so waiting as long as 20 minutes (or even longer) is not unusual. Don't worry about Ariel taking a break while you're in line. They'll cut off the line so that she can see everybody before leaving or she'll just leave for a moment before coming back onstage.
Length of Show: Varies for obvious reasons but don't expect much more than a minute with Ariel.
Queue Description: The whole area is decked out to look like an undersea cove, but the queue inside of it is just a chain corral.
Ride Access: Impairments of any type can be accommodated, speak with one of the cast members if needed. The queue is wheelchair and ECV accessible
Service Animals: Yes
Audio: No assistive devices are needed, though the character cast members are well trained in working with just about any type of impairment. Ariel is a character that is allowed to speak.
Weight and Size Issues:
Height Restriction: No
Child Swap: No
Other Issues: Although there is no child swap, one parent may want to wait in line without the children, then the family can join again together as that parent nears the beginning of the line. This line can get long.
