2. I'm sorry, because today is a holiday, and some people (departments) are off today (there is no office or no one is working). Can you call again on Monday to inquire about this matter?
3. When you check in, you can get two free tickets to the Trade Fair Exhibition Hall with your room card.
I'm sorry I didn't help you. I hope I can serve you next time.
5. I'm sorry I don't understand what you want (or I can't answer your question). Did you transfer the phone to the assistant manager in the lobby and let him communicate with you?
