user
we have quite a few , i am sure we'll be able to get you where you want to go . where is that , exactly ?
assistant
i would like to go to leicester and leave on friday .
user
i have quite a few trains that fit your criteria . is there a certain time you need to leave or arrive by ?
assistant
departing from cambridge and i want to arrive somewhere around 20:00 , can you get me 7 tickets and i'll need the reference number too .
user
the tr2508 arriving at 19:06 sound okay to you ?
assistant
that sounds great , thank you . could you book that for me for 7 people ? i will need the reference number as well .
user
i completed your booking . the reference number is c11mobv7 . is there anything else i could help you with ?
assistant
yes , i also need to find a place to stay . preferably 4 stars and a guesthouse .
user
sure ! our database contains 18 guesthouses rated 4 stars . to narrow down the search , could you tell me in what part of town you would like to stay ?
assistant
i definitely want to stay in the east part of town .
user
i have 6 entries matching your request . would you prefer cheap or moderate price range ?
assistant
the price range does not matter , but could you pick 1 and book it for 3 nights for 7 people starting tuesday ?
user
i am sorry . there are no rooms available for that stay . can you choose a different day or shorter stay ?
assistant
how about 1 night ?
