Can the hotel balcony be sealed?

Of course. According to the information about hotel safety, the hotel balcony can be closed. Hotels are public places, which mainly involve hygiene and safety. Safety comes first. Windows and balconies must be closed, but they should not affect the lighting and ventilation, and should also be dust-proof and fly-proof. High-rise buildings should not have balconies or closed balconies as far as possible, which involves many problems such as strong winds, heavy rains, falling objects and injuries.
