I work in a hotel. I don't know how to send a text message to invite dinner. Thank you, everyone.

I work in a hotel. I'll give you some reference. Direct: This is XXX from XXX Hotel. You haven't been to our hotel for a long time. Are you busy? We miss you very much when we have time to visit our home. Indirect: Hello, are you Mr. XXX? This is XXX from XXX Hotel. Why don't you come over after all this time? Did we do something wrong to make you unhappy? Give us suggestions when you have time, so that we can improve. Some you can look up online, and many others. I wish you a promotion step by step.
