U: I'm looking for a train leaving Cambridge traveling to Kings Lynn.

S: What day will you be traveling.

U: I will be traveling on Wednesday and it needs to leave after 15:15 if possible.

S: TR8890 leaves at 16:11, would that work for you?

U: Yes, that would be great. Can you book that for me for 5 people and be sure and give me the reference number?

S: I've reserved 5 train tickets for you on the TR8890. Reference number is R0XHVN6M, and your total due is 49 GBP, which is payable at the station. Need anything else?

U: I also need a place to a place to stay in the moderate price range with free wifi.

S: Would you prefer a hotel or a guesthouse?

U: It doesn't really matter, but I'd like it to have a 4-star rating, please.

S: There are 11 places fitting your needs in the east, north and south of town. Do you have a preference?

U: Please pick one that has free parking.

S: How about the Acorn Guest house? It is rated 4 stars and is on the north side of town. They offer free parking and internet.

U: Is it centrally-placed and accessible?
S: The Acorn Guest House is around fifteen minutes outside of the city center, which some customers found to be inconvenient, but some felt the location felt more safe.
