It depends. If it is an international five-star hotel, English is necessary, but different departments are different. If it's a guest room, it doesn't matter much (your period will do). If you want to know simple English, such as ordering food, the front desk has higher requirements. If you want to be able to communicate, the English of local five-star hotels is not as strict as that of international ones. Even at the front desk, the English requirements are not too high, but there are still.
