I booked a room at Home Inn official website, and I deleted the confirmation information.

When you arrive at the store, you only need to give your name and show your identification, and you don't need to send a text message.

If you really want to send a text message, you can call the customer service at home and ask the other party to send it to you again. Because some information, such as address and telephone number, may be useful to you.

If you book a hotel like Home Inn, you can definitely stay after noon 12. If there is a room available, you can check in that morning. If you want to check in early, you can call first.
