How to write the warm reminder that the hotel put in the guest room?

According to the experience of our hotel, it's probably like this.

Dear guest/Mr. X:

Hello, welcome to XXX Hotel. The hotel specially provides XXX (fruit milk) for you in * * * (optional according to your needs). If you need anything else, you can call the front desk at 12345678. I sincerely hope that you will enjoy your stay here.

Room manager/room manager XXX

You'd better put a business card next to it. If it is an important guest, it is best for the manager to sign it himself.

If you know the guest's last name in advance, write it in front of the small card. It makes people feel warm, which is very important.
