/kloc-Can a 0/7-year-old sister book a hotel for two?

/kloc-You can book a hotel stay under 0/6 years old.

1,/kloc-minors aged 0/6 can go through the check-in formalities at the hotel and get the key or room card after obtaining the ID card;

2./kloc-Minors under the age of 0/6 (those who have not obtained their own ID cards) can also check in at the hotel with other people's ID cards; But I can't get the key or room card for booking. You need an ID card to get a key or room card.
