absolutely . what day do you need to get to cambridge , and at what time ?
assistant

user
there are trains that meet those requirement -s leaving once an hour starting at 05:40 .

can you assist me with booking 1 ?

lets narrow down the time a little , the tr 3802 leaves at 17.40 and arrives at 20.23 so that gives you a little extra time , would you like me to book you ?
assistant
that would be great . i also would like to book a guesthouse for my stay .
