Are there age or height restrictions for kids in elevators and on outdoor decks?

For elevators, there are no official age or height restrictions — just common sense rules like not letting toddlers push buttons alone. For outdoor decks on cruise ships, hotels, or apartment buildings, rules vary: many cruise lines require a minimum age (like 5 years old) or height (like 42 inches) for open railings. Your safest move is to call ahead or check the specific policy, especially for cruises. Otherwise, keep a hand on the kid and don’t overthink it.
