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?
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.
