My name is Alexis and I want to make a reservation at Old Town Inn from May 5th to 30th. 
Alright, the Old Town Inn ticks all of your boxes, can I book this room for you?
I've changed my mind and want to stay at Shadyside Inn
Alright, the Shadyside Inn ticks all of your boxes, can I book this room for you?
sure
OK, I've successfully completed this Hotel booking for you!
I've changed my mind and want to stay at Hilton Hotel. 
Alright, the Hilton Hotel ticks all of your boxes, can I book this room for you?
Yes. There's this great travel blog that I rely on and that its never let me down on my journeys.
Is there anything else that I can do for you?
I would like to change my reservation to 10th-26th the following month.
I'm very sorry, but there is no room available at the Hilton Hotel for your requested dates.
I don't really want to go to London because my partner's brother is a bit of a show-off, but obviously I'll be going to the wedding.
I am sorry, I don't quite understand what you mean. I am only able to help you reserve a hotel room.
