Can i leave and come back for my toy story mania boarding group?

The provided evidence does not address the policies of a Toy Story Mania boarding group. Because group membership rules vary widely—depending on whether it is a Disney attraction, a fan club, or a private event—there is no definitive source confirming that leaving and rejoining is allowed or disallowed. If the group is organized by a theme park or official Disney entity, typical practice is that guests can return to the attraction after exiting, though wait times and reservation rules may apply. For fan groups or online communities, rules are set by the group administrators and can differ; some allow re‑entry, others require a new invitation. Without specific documentation from the group or its organizer, it is impossible to state with certainty whether you may leave and come back.
