A: Hi, I need to change my reservation.

B: Sure, what's your reservation number?

A: It's 123456.

B: Okay, what changes would you like to make?

A: I need to change the date of my arrival. Instead of arriving on the 15th, I need to arrive on the 17th.

B: Okay, let me check if we have availability on that date. Yes, we do. Would you like to keep the same room type?

A: Yes, please.

B: Alright, I have updated your reservation. Is there anything else I can help you with?

A: No, that's all. Thank you.

B: You're welcome. Have a great day!
