What are the requirements for taking a nanny to a hotel when traveling?

The documents needed to stay in the hotel are: now you only need to use everyone's ID card, instead of marriage certificate and household registration book. Children who don't have ID cards had better bring household registration books to prevent large-scale activities in that city from needing documents. Generally speaking, you don't need to bring an available student ID card. Driving licenses to most cities in other places are not recognized as ID cards, so it is better to bring ID cards.
