Please have a look at the English tips of the hotel.

Dear guests,

Welcome to XX Hotel!

If you are satisfied with our service, please tell your friends. If you are not satisfied, please call our quality service number: xxx. Thank you!

LZ is trying to express this, isn't it?

Personally, I think LZ's English skills are good, hehe, here is my personal translation (I am a college student, majoring in international trade, hehe)

Warm tip: (lz is tip, to be honest, tip just means tip, and I really don't know anything else. Maybe I'm not good at studying, so I changed prompt here. )

My dear guests,

Welcome to the hotel! (The hotel here refers to the hotel where LZ is located, so it is better to add that, hehe)

If you are satisfied with our service, please tell your friends. If you are not satisfied, please call our excellent service number: XXX. Thank you!

As for the writing, I personally, like lZ's, have also asked my classmates, (I'm afraid the translation is not funny, o(∩_∩)o) They all say OK, the simplest and most commonly used, hehe, I hope I can help lZ.
