I can look that up on my end for you, instead. What would you like to know about the Alpha-Milton? All set. Your reference number is ND2FGBF1 . There are several trains going to Stevenage. What day would you like to depart? Okay there are 10 trains. What time would you like to leave after or arrive by? I am sorry we do not have a train fitting your needs for Monday at 18:30.
One moment while I look up the alpha-milton guest house for you. I'd like to book a room for two people on Sunday for two nights, please. I will also need a train to Stevenage. I'll be leaving on Monday. I would like to arrive by 18:30, please. Are you quite sure? I don't mind if I arrive a bit earlier, but I need to be in Stevenage by 18:30 on Monday.
