Some facilities might have both public TTY's and ones that are used at a specific location like a switch board. Many older couples enjoy a visit to the zoo. Sometimes, one of the spouses requires assistance to use a restroom. These restroom facilities allow personal care assistance without creating a difficult or uncomfortable situation in the public washroom. Other guests find these restroom useful as well.
Family restrooms are useful for single parents or one parent with several children.
Some groups, such as those with disabilities, might also need assistance in the restrooms. Many times the group leaders are of the opposite sex. Typical restroom facilities would make this situation difficult to supervise. Some individuals or groups might have a variety of medical needs and require special equipment to enjoy their zoo visit. If you are visiting and have people with medical needs, it might be helpful to alert security of your visit.
