Alright, there are 18 hotels in the moderate price range. Is there a particular part of Cambridge you would like to stay in? Are you open to guesthouses? We have several 4-star moderately priced guesthouses. I could recommend Avalon in the north of town. Okay, I can go ahead and book that for you. I would just need to know the day your checking in, how many nights you need, and also how many people? The address is 62 Gilbert Road. The Avalon offers free Wifi but is does not have free parking. Is there anything else I can help you with? I just need your destination and where you are leaving from please. You have a choice of three trains. One leaves at 19:17, one at 21:17, and one at 23:17. Will any of these three trains work for you?
Hello. I need to find a hotel in Cambridge in the moderate price range. I'd like it to be a hotel with 4 stars if possible, are there any options? That sounds good. Please book it. Sorry, I don't need to book it now, but can you tell me their address and if they have free parking and wifi? I am also looking for a train to leave on Sunday after 18:00 I'm going to Cambridge and I'll be at london kings cross. The 19:17 one would work. Can you give me the arrival time for that one.
